Nevermind the last email I sent with the stack trace. I got this
crash a couple of times and gdb never seems to core in the same
place twice. I think the problem is actually with gdb rereading
symbols from and applicaiton when you recompile tha app in between
runs in the debugger (without quitting the debugger). My app
was also dying from a call to assert(), but I am not sure if
that made a diff.
I was running on Red Hat 6.2 when I got these crashes by the way.

This came up last week with Tom. Fernando has some state on it. What's
happening is that the variable code that gdbtk uses (which I guess gdb
is going to slowly migrate to?) hangs on to a lot of pointers to the
symbol table and obstacks. When the symbol table is re-read (and maybe
even if you just re-run the executable), all of these references are
bogus.
We found out that a hook which is supposed to clean this up is not being
run anymore. I think this is either the clear_file or no_inferior hook.
Both the variable windows (Locals and Watch) and the SrcTextWin
(variable balloons) should be erasing any variable objects whenever the
inferior is killed/re-run or has symbols re-read.

Keith is absolutely right.
We are working on a fix. I proposed a change to gdb and I will probably get it approved soon. It
just does what Keith says, it makes sure the hook is run whenever this data becomes stale.
The next insight snapshots won't have this problem.
