Ah, this explains why Eli saw the problem in Emacs in a deterministic manner, whereas I see it only with 0.3% probability in my tests on 64-bit mingw. > I installed > into Gnulib the attached patch, which I hope fixes the Emacs problem > without changing glibc's generated code (once this gets migrated back > into glibc). In 10000 runs on 64-bit mingw, your patch went from 27 test failures to 11 test failures. So, we're still at ca. 0.1% probability (*), far above the 62^-6 or 10^-10 probability that one would have hoped for. (*) I wouldn't consider these measurements reliable. Maybe the probability did not change, and what I'm seeing is merely a measurement fluke. Bruno
