Description Bjoern Jacke 2005-08-10 11:04:55 UTC

up to 9.3 I was using LD_PRELOAD=/usr/lib/libaoss.so with alsa dmix globally
which worked great at let me play sound from any application simulanously
without noticable latency. In 10.0 it doesn't work anymore with some X11
applications, some applications still work ...

It can simply be reproduced with xcalc:

LD_PRELOAD=/usr/lib/libaoss.so xcalc
Segmentation fault

reinstalling the alsa RPM from 9.3 on the same system makes it work again

Are you sure that the 9.3 alsa.rpm works on SL10.0 system (ie. new gcc4/glibc)?
I still get segfault with 9.3 alsa.rpm.

It seems that fcntl(fd, F_SETFD, xxx) causes segfault.  Interestingly, other
F_XXX seems OK.

Jaroslav, any clue?

OK, I found the culprit.  It's a missing initialization in fcntl wrapper.

The fixed package is submitted to STABLE.
