But I tried the pre compiled libraries in http://download.fedora.redhat.com then used the downloaded libc.so, libdl.so and libphread.so at run time. -> Fedora development version glibc-2.9.90-8.1.i686.rpm Newer than mine. Found in : http://download.fedora.redhat.com/pub/fedora/linux/development/i386/os/Packages/ -> Fedora release version glibc-2.9-2.i686.rpm Older than mine. Found in : http://download.fedora.redhat.com/pub/fedora/linux/releases/10/Everything/i386/os/Packages/ The bug is still there with both these versions. I've tried using another glibc (eg ubuntu), but I must say I have difficulties looking into them... Perhaps someone has Fedora Rawhide installed, and could test ? If this is possible he sample program is alsa_main.cpp, available at : https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4426 Cheers, Nicolas > On Mon, 9 Mar 2009 Nicolas.Castagne@xxxxxxx wrote: > >> Hi Jaroslav, Takashi and all, >> >> thx for you answers. >> >> >> Takashi : >> > Hm, I don't see any reason, and I cannot reproduce a crash on my >> machine... >> >> I can reproduce it on my three Fedora10 machines, using 2 hardware. >> >> Jaroslav >> > I would suggest to comment out code from >> snd_config_update_free_global(). >> > Try to comment out snd_dlobj_cache_cleanup() at first.
