You didn't say which platform you're trying it on. If it's GNU/Linux,
there have been a number of recent fixes in the development sources
with regard to being able to attach to a multi-threaded program. If
you haven't done so already, you might want to fetch and build a copy
of the developement sources. Otherwise, you should provide us with more
information so that we can try to fix the problem in GDB.
