Hello all, I'm running a stock sarge machine with the 32bit 2.6.8 kernel on a AMD64 3200+ machine. I'm using some unstable and demudi packages. Problem I'm having is that a few apps (actually almost all my v4l apps) crash when I try and capture video. Actually there is no fault, but the software hangs. I traced it down to the use of pthread_join() which is where the code hangs. (I've been doing a backtrace after manually killing the application) I tried upgrading my libc6 to 2.3.2.ds1-22.d still getting the same crash. Here are a couple examples of traces: (gdb) bt #0 0xffffe410 in __kernel_vsyscall () #1 0x40128f18 in pthread_join () from /lib/tls/i686/cmov/libpthread.so.0 #2 0x44bd97bd in videoV4L::stopTransfer () from /usr/lib/pd/extra/Gem.pd_linux #3 0x44bd504c in pix_videoNEW::stopRendering () from /usr/lib/pd/extra/Gem.pd_linux #4 0x44b0111e in GemBase::gem_startstopMess () from /usr/lib/pd/extra/Gem.pd_linux #5 0x44b01382 in GemBase::gem_MessCallback () from /usr/lib/pd/extra/Gem.pd_linux #6 0x0809ba47 in pd_typedmess () #7 0x00000000 in ?? () (gdb) bt #0 0xffffe410 in __kernel_vsyscall () #1 0x40128f18 in pthread_join () from /lib/tls/i686/cmov/libpthread.so.0 #2 0x42a86440 in pdp_sdl_setup () from /usr/lib/pd/extra/pdp.pd_linux So what should I do to try and solve this? What version of libc6 should I be using? Are there known bugs with my configuration and pthreads? I'm dependant on getting this machine working, so I hope someone has a suggestion. I'd be happy to do whatever tests to break the issue down further. Thanks all. B.
