Yes, gdb on Windows just isn't as good as you'd expect.

There are two things you could try:

    * Upgrade. 6.8 is much better than previous versions.
    * If possible, attach gdb after startup instead of starting your
      executable from it.

If that does not help, go the old-fashioned way and printf() your debug
info from the code. Sadly, this is way less intrusive than using gdb.

Not necessarily. It could also be a memory corruption elsewhere that
wasn't triggered or didn't strike before.

No, unfortunately not.

Not intentionally.
Also, there are no constructors that would be called automatically.

There's actually very little debugging aid available on Windows. On
Linux, you could run Wine under valgrind supervision and run your
application in it. I don't know how valuable the results of this
approach are, though.



Hope this helps,
