[ptxdist] alsa-lib crashes with current OSELAS.Tollchain-2011.11.0 toolchain (arm-v4t-linux-gnueabi)

[Juergen Beisert]

Hi,

someone here who has tried to run something alsa-lib related with our current 
OSELAS.Tollchain-2011.11.0?

Here all programs are crashing with a "Segmentation fault" if they are using 
the 'libasound.so' at run-time. There are reports about issues with alsa-libs 
and glibc-2.14 [1].

All I can say is, the same alsa-lib release runs without a problem on a system 
build with the OSELAS.Tollchain-2011.03.0 (and so with the older glibc-2.13).

I tried with 'catchseg' but the output is very 'strange' and not helpfull:

root@mini2440:/ catchsegv aplay /mnt/music.wav

Any idea how to debug a toolchain/glibc issue like this?
