It may sometimes crashed in the glWaitSync function
When a crash occurs, the length of time to the video playback is not fixed. It sometimes crashed in a few minutes, or in 10 hours under the same environment
The video decoder is FFMPEG which integrated in the chrome kernel
This crash will occur once GPU hardware acceleration is enabled. Turning off the acceleration is without crash.

I have a local wiki (MediaWiki 1.38.4 ; Apache with xampp) that worked perfectly for a few weeks, but today started giving me errors with the TemplateParser.php and now is completely unnaccesible and shows the following error details:

I have already restarted the system, re-installed the wiki and copying the manual backup I had of the files and the database, and no solution. Any ideas?
I installed MediaWiki on my Mac with MAMP (PHP7.2.10 and MySQL 5.7.23 InnoDB). No error occured and everything except the search works. It shows the following error instead of a result:

A first attempt was to start the web updater, but /mwconfig/ only allows the download of the LocalSettings.php. No way to actually start it.
Any ideas? Thank you!
I think its a generell Problem with the MySQL installation. Reinstalling the server fixed it.
I recently installed MediaWiki in localhost on Debian 7 System. But after the installation, I got the exception Fatal exception of type MWException. I reviewed all reported bugs, but they do not apply to me.
PHP 5.4.4
phpmyaddmin....
As written in the comments, edit your LocalSettings.php file and add this line at the very end:
$wgShowExceptionDetails = true;
Try reloading the page that gives you that error. You're likely to see what's called a backtrace... here is my example:
#0 /Users/user/www/extensions/LocalisationUpdate/LocalisationUpdate.class.php(553): LocalisationUpdate::filename('it')
#1 /Users/user/www/extensions/LocalisationUpdate/LocalisationUpdate.class.php(36): LocalisationUpdate::readFile('it')
#2 [internal function]: LocalisationUpdate::onRecache(Object(LocalisationCache), 'it', Array)
#3 /Users/user/www/includes/Hooks.php(255): call_user_func_array('LocalisationUpd...', Array)
#4 /Users/user/www/includes/GlobalFunctions.php(3883): Hooks::run('LocalisationCac...', Array)
#5 /Users/user/www/includes/cache/LocalisationCache.php(796): wfRunHooks('LocalisationCac...', Array)
#6 /Users/user/www/includes/cache/LocalisationCache.php(426): LocalisationCache->recache('it')
#7 /Users/user/www/includes/cache/LocalisationCache.php(310): LocalisationCache->initLanguage('it')
#8 /Users/user/www/includes/cache/LocalisationCache.php(245): LocalisationCache->loadItem('it', 'fallback')
#9 /Users/user/www/languages/Language.php(3978): LocalisationCache->getItem('it', 'fallback')
#10 /Users/user/www/languages/Language.php(230): Language::getFallbacksFor('it')
#11 /Users/user/www/languages/Language.php(189): Language::newFromCode('it')
#12 /Users/user/www/includes/Setup.php(497): Language::factory('it')
#13 /Users/user/www/includes/WebStart.php(161): require_once('/Users/user/3d...')
#14 /Users/user/www/index.php(55): require('/Users/user/3d...')
#15 {main}
The first line is the one that stopped the execution, causing the exception. If you can identify the problem (in my case it's the LocalisationUpdate extension) it can be very easy to fix. Again, in my case it's enough to open again LocalSettings.php and comment out or delete the line:
require_once( "$IP/extensions/LocalisationUpdate/LocalisationUpdate.php" );
There could be a problem with caching, try to use
$wgMainCacheType = CACHE_NONE;
My program, which draws a small animation, uses glut and cuda, and is written in C++, hangs after a while, and I see the following trace in the debugger when I interrupt it a few seconds after it hangs:
Program received signal SIGINT, Interrupt.

(This is the top of the stack trace; the rest is my own functions, one of which calls cudaMemcpy.)
If I try to interrupt right the moment after it hangs, the trace looks like this:
#0 0x00007fffffe0026d in __spin_lock ()
#1 0x00007fff880f855b in pthread_mutex_unlock ()
#2 0x000000011303ad89 in cuGraphicsGLRegisterBuffer ()

#10 0x00000001001d70c4 in cudaGetExportTable ()
#11 0x00000001002098a5 in cudaMemcpy ()
I don't know how to approach this. cudaPeekAtLastError does not give any error before that call to cudaMemcpy. I also know that I can run the programs included in nvidia's SDK. Further, the program runs for several seconds before hanging, which means that all the cudaMemcpy calls before it hangs execute without producing errors, so there doesn't seem to be any issue specifically with how I call cudaMemcpy, or with pointers being incorrectly allocated (if they were, I would expect cuda to just generate an error, not hang).
The card is GeForce 9400M, Cuda driver/runtime 4.2, Cuda capability 1.1.
Any advice?
I'd guess you're having a pointer problem, such as trying to copy past the end of a buffer (either source or destination), or referencing a bad pointer altogether. Once you start stepping on invalid memory, don't expect any sane error reporting or useful backtrace.
Looking at your backtrace, the GLRegister calls could be called because you're unintentionally trying to copy from a device memory space mapped to OpenGL.
Try cuda-memcheck, and/or valgrind. Or, since is easily reproducible, start by verifying (by debugger or by printf) the values you're passing into memcpy. Or, start manually binary-searching by disabling parts of the code until things work again.
I am running an executable that uses libmysqlclient.so.15 on a 64bit kernel & 32bit user space compatibility mode.
Once in a while, my program hangs on something from libmysql:
