If the crashes in gmalloc don't happen unless glib is linked in, then
it's possible that its memory management conflicts in some way with
gmalloc (and possibly ralloc, if Cygwin uses that as well).

Thanks, I think that's the problem: the new code invokes glib
primitives before the memory allocator is set up on Cygwin, which is a
no-no.  I moved the glib SIGCHLD tickling to later, in trunk bzr 113142;
does that help?

No. Rev. 113146 fails in similar manner:

GLib (gthread-posix.c): Unexpected error from C library during
'pthread_setspecific': Invalid argument.  Aborting.
Makefile:232: recipe for target `compile-onefile' failed
make[3]: *** [compile-onefile] Aborted

Sometimes the bootstrap hangs:

make[3]: ingresso nella directory "work/emacs/Work/lisp"
Compiling work/emacs/src/../lisp/emacs-lisp/map-ynp.el
make[3]: uscita dalla directory "work/emacs/Work/lisp"
make[3]: ingresso nella directory "work/emacs/Work/lisp"
Compiling work/emacs/src/../lisp/cus-start.el

and I cannot break it with CTRL-C. To kill the "bootstrap-emacs" process I need to kill it with Windows task manager. The Cygwin "kill -9..." command doesn't help... it helps only to kill some "make" processes...
