In the thread you referenced "http://sourceware.org/ml/gdb/2008-01/msg00032.html" it looks like a SIGILL was happening after a breakpoint and there was valid gdb backtrace data present. What I'm seeing is there is NO backtrace data available after a SIGILL, this makes it impossible to use gdb for debugging the cause of a SIGILL in my application. I think my problem is more like that of the following thread: "http://sourceware.org/ml/gdb/2007-03/msg00155.html" In fact that thread was started by a co-worker of mine, we were never able to get it working and gave up on it but now I want to get to the bottom of the issue and get gdb working for backtracing SIGILLs on an ARM EABI GLIBC system. Summery of my system: gdb version: 6.8 glibc version: 2.5 ARCH: PXA270 (xscale) Linux Version: 2.6.23 (Distro: OpenEmbedded) Regards, Shane
