[Bug symtab/10295] New: gdb segmentation fault in 'gnuv3_baseclass_offset' while printing a value

[tfogal at alumni dot unh dot edu]

Using gdb-6.8-debian, as well as a current archer branch
(archer-tromey-delayed-symfile, 94cd6b61db67d25c1f490f7b7a2fbf6ca33de917), gdb
produces a segmentation fault as I try to print a std::vector<float>.  The
vector in question is causing an assertion failure in my program, which has
debug iterators enabled.

The program being debugged is an MPI program, making debugging it somewhat
involved.  To do so, I force the program to busy-wait in a tight loop after
starting, giving me time to `gdb -q -ex "attach <pid>"'.  Then I use `set
variable' to force the loop to exit.

I will attach a core and the output of 'bt full' in a second...

Scratch the promise about the core file: it's 425 megabytes.

If you're really interested, you can download it here:

I think this is a dup.
If you try a new gdb and this bug still exists, please reopen or refile.
