Thanks. The crash occurs when I mouse over a variable in the source
window after the inferior stops at a segfault. The inferior's stack is
quite probably corrupt. I think Insight is crashing when it tries to
dig out the value of some variable from the inferior's corrupt stack.
After Insight stops normally at the inferior's segfault and before it
crashes (ie: before I mouse over the variable), I see three calls to
throw_exception(). Backtraces are included below. In this run, the bogus
interp->varFramePtr was 0xbfffcc84, and I see that being pushed on the
TCL stack between the first and second calls to throw_exception. I did
not see it being popped, at least not with a call to Tcl_PopCallFrame.
It was pushed here:
