Re: Debugging under SMP problem

[Chris Faylor <cgf at cygnus dot com>]

There is only one "cygwin component" that has a version number of 1.1.2, and
that's the Cygwin DLL.

I regret that I don't understand why you're seeing this problem if you are
truly using that DLL.  The only advice I can offer is to make absolutely sure
that some older DLL is not in your path.  "cygcheck -r -s -v" should tell you
if that is the case.
