debugging a signal 10 while in libc_r

[Joost Bekkers]

Hello

I have this multi-threaded app which will crash about once a month. gdb tells me the following:

Program terminated with signal 10, Bus error.
(gdb) where
#0  0x817b5a7 in _thread_kern_scheduler ()
#1  0x0 in ?? ()

I have no idea how to continue or even what to look for. Can anybody give me some tips/urls?

The app is running on 4.3-R (ancient I know, can't seem to make time for an upgrade)

thanks
