[gentoo-dev] random gdb "debugger segfaults"

[gentoo-dev] random gdb "debugger segfaults"

[Burton Samograd]

Hi,

I'm not sure if this is a gentoo problem, but I figured I would get a
better response through this list than gentoo-user.

I'm working on a new C program and I'm getting a number of debugger
segfaults when running gdb.  I've never had such a vital program as
gdb crash on me before, so this has gotten me a bit worried about
possible library mismatches or problems with newer versions
gcc/binutils/gdb working together.

I'm working with shared libraries in this application for the first
time, and I thought that gdb might be a bit flakey with this type of
dynamic symbol allocation.  Anybody have experience with this?

I don't know if there's a current solution, but I thought that I
wouldn't be alone is seeing these problems and that others might have
already found the source (and solution). Currently I'm running:

gdb 6.0
gcc 3.3.2-r2
binutils 2.14.90.0.7

Note that gdb does work, but crashes rather randomly (as in, I can't
see a definite pattern that I could nail down to an actual bug)
requiring a restart, which is a bit irritating but not life
threatening.

What kernel, and which optimizations are you using. Further there could of 
course be the standard bad power/bad mem/other flaky hardware problems

kernel: vanilla 2.4.21 with preempt patch
gentoo cflags: CFLAGS="-O3 -march=pentium2 -pipe"

My application has no optimizations enabled at the moment with the
only CFLAG being -g.
