  gdb tends to suck for C++, although it's usable for C.  There are some
graphical frontends too (ddd and insight, I think?)

  For weird segfaults you could try electric-fence, which can help you catch
problems like references to freed memory.

  The program "gmemusage" shows you a realtime display of memory
usage.  If there's a leak triggered by an interactive event (eg:
"I click on the button and it leaks 5MB"), this is a good way to
find it.
