[Sorry, I accidentally sent an unfinished reply. I'll restart.] Yes, I agree in principle, but I'm not yet sure it's a Cygwin bug, and I haven't been able to come up with a simple test case that exhibits the problem. My naive attempt didn't work: I wrote a little C program that tickled Glib exactly as in process.c. I ran it thousands of times without an error. So I have to try to figure out what's different during bootstrapping. And Emacs's gmalloc.c may be part or all of the problem too. That's not compiled on GNU/Linux. I'd like to keep trying to track this down for a while before asking on the Cygwin list. Ken
