Problem with glibc test

Thanks so much for the detailed response. I couldn't find any bug reports that seemed to match this, but then I don't have much experience searching for them. I tried this same test in Ubuntu, and it seems the bug is still there, as of glibc-2.7. I've wrestled in frustration with glibc a bit over the last few days, and I'm definitely not prepared for the cvs build needed in order to report the bug.
So I disabled the test and moved on. I still get the expected posix/annexc and nptl/tst-cancel1 errors. I also see:
make: *** [nptl/tests] Error 2
make: *** [check] Error 2
but I think that's just the nptl/tst-cancel1 error propagating itself.
Thanks again for the help! It's much appreciated.
