Severity: important On the Emacs trunk, the changes in revision 109788 (Special MEM_TYPE_SPARE to denote reserved memory) cause Emacs to dump core on x86 Fedora 15. The previous trunk revision 109787 works fine. The problem goes away if I disable optimization, by configuring with CFLAGS=-g3.
This depends on values on a C stack, which aren't predictable in general. But an issue looks almost obvious, should be fixed in 109791. Dmitry
