I think you did, as it works for me. I just tested again. I'm
attaching the output from

make check TESTS="" TESTSUITE_FLAGS='-v -d 22'.

As you can see, it goes on for quite a while before it segfaults,
and no sign of the errors you see. I had a breif look at this
new bug and it looks as if there's a problem when accessing v7
or v8 (first line in main in main.c, line 90 in stresstest.at)

Perhaps something along the lines of:

http://cygwin.com/ml/cygwin/2004-09/msg01101.html

I think this bug is present for all of MSVC, MinGW and Cygwin,
so it smells like some generic windows problem...

*sigh*

Cheers,
Peter
