Hi all,
It seems to be a well known problem that gdb cannot reliably break in
ctors and dtors, and that the bug has been around for years. I'm sure
it will be with us for years to come. :(
So I'm looking for a workaround... any suggestions? Is there a way,
with the command line, to make gdb break on all versions of a ctor/dtor?
Right now my workaround is to sprinkle Debugger() calls where I need
them, but that's a huge PITA. Also Xcode generally crashes stepping out
from __pthread_kill().

So I am absolutely stuck for some way to debug within my dtors!
