How to catch GDB crash

[Dmitry Smirnov <divis1969@mail.ru>]

Hi,

I've encountered the very annoying problem with GDB. While debugging, it crashes for some reason and I cannot catch this moment. I have a possibility to attach to the running process with another GDB, but it does not help. Perhaps, there is some way to catch some system exception or something similar?

I'm using a litle bit complex setup, so there is no much freedom (at least I cannot simplify the situation). First, I'm debugging from Eclipse (and it looks this crash happens only while running from Eclipse, I've tried from commad line - there is no crash). The debugger I'm using is cross-compiled arm-elf-gdb. It is compiled on windows (i686) platform:
GNU gdb (GDB) 6.8.50.20080620
...
This GDB was configured as "--host=i686-pc-cygwin --target=arm-elf".

I doubt this can be linked to GDB version. I recall I've seen this crash earlier with arm-elf-gdb 6.5 from GNUARM. I was just skipped this crash somehow but now I cannot continue my job.

This arm-elf-gdb is running against skyeye simulator as a remote target.

As you can see there are many possibilities for mailfunctioning software (Eclipse, GDB, skyeye). But the only way I can find the root cause is to debug the crash in arm-elf-gdb. While crashing it attempts to create the crashdump file, but it is incomplete and Cygwin gdb cannot recognize it. Typically it contains just three lines:

Stack trace:
Frame     Function  Args
0022E268  7C802532  (00000058

If attached, Cygwin GDB just reporting me:
Program exited with code 037777777777.

Is there any way to stop arm-elf-gdb on some critical error?
