[vlc-devel] Application using libvlc crashes

[jboileau]

Hi,

I am getting reproductible crashes using libvlc-control.dll 0.9.0
(vlc-0.9.0-git-20080310-0003-win32.zip) . This may be in my usage of
it but I hope someone can help me find a cure. This application runs
under Windows. I stress it by playing and stopping 6
libvlc_media_instance_t playing MP3s and 1 libvlc_media_instance_t
playing an AVI. I start all of them, wait 3 seconds, stop them all,
wait 3 seconds, ad infinitum. After about 15 minutes I get a crash.
The last one I got ended with the following messages:


HEAP[MediaScriptEngineTester.exe]: HEAP: Free Heap block 110a2e68
modified at 110a2fb4 after it was freed
Unhandled exception at 0x7c901230 in MediaScriptEngineTester.exe: User
breakpoint.


And the following stack trace.
