crash in gdb-6.3.50.20050906 and 6.3 (release)

[Matthew J Fletcher <mfletcher@serck-controls.co.uk>]

Hi

before i file a bug report im posting this here for advice.

this crash comes only seems to occur when i try to inspect local variabes in a 
large (16,500) line module of c++ code using lots of stl.

in other modules of the same program its fine.

the code was compiled for i486-unknown-elf using gcc 3.4.3.

im not at all sure about how to break this down into a smaller testcase as it 
seems that the size of the module may contribute to the problem.

shown is a backtrace, and some info about the stackframe that the crash 
occured in.
