Hi all.
I have a multi-threaded application that has benn running ok on my (permanent?)
Cooker system, till latest glibc-gcc upgrades. Now, I just dies with a
Segmentation fault.
>From gdb, I get:
Program received signal SIG32, Real-time event 32.
0x4036f3b5 in pthread_getconcurrency () from /lib/i686/libpthread.so.0

I have looked through the cooker list, but the only thing I found was a
similar problem with Mozilla many time ago...
I have read through manuals and they say that signals 32+ are 'real time
signals', and that linuxthreads use the first 3 internally. And that
gdb should not stop the app with one of that signals, to debug MT apps.
I suppose that the hang point in gdb is not the real one, gdb stops there
and should not do it.
Problem with glibc build ? With gdb ?
If someone guesses why gdb hangs, then I would try to see what makes my
code hang...
TIA
