I can't reproduce that (also on W7). How big is bigfile-test.dll?
Eric, does git use pthreads and fork from a thread, by any chance?
/me rummages around in git.git
Well, it certainly has both pthread_create and fork calls in the same
files (at least run-command.c), although I'm not quire sure if it tries
to actually fork from a pthread rather than from the main thread.
Ok, thanks anyway. I think I know what happens. Two days ago I thought
it is a good idea to use the Windows-provided stack from CreateThread by
default (== if the application didn't provide its own). Too bad that
Windows creates the stacks typically in the lower regions of the
processes VM. I guess I have to revert that, so that pthread_create
always uses a self-created stack again. Oh well. So much for "good
Just reverted in CVS. Will show up in the next snapshot.
