Lord knows it drives me bonkers.  I didn't know exactly when it
happened (never bothered to look it up).  I seem to recall that you can
also crash GDB a number of different ways with this, which are probably
separate bugs.  This is a bit garbled of a report, I realize; I'm
always neck-deep in something else when it happens...

I have found that GDB will unreliably segfault when I set a watchpoint
using a convenience (or history; are those handled the same way?) variable
and then recompile and rerun the program, causing it to be reloaded.
