Yesterday, I met Emacs crash this way:

Program received signal SIGSEGV, Segmentation fault.

But, this Emacs was compiled before these changes:

2006-03-10  Kim F. Storm  <storm@cua.dk>

	* alloc.c (USE_POSIX_MEMALIGN): Fix last change.

2006-03-09  Stefan Monnier  <monnier@iro.umontreal.ca>

	* alloc.c (USE_POSIX_MEMALIGN): New macro.
	(ABLOCKS_BASE, lisp_align_malloc, lisp_align_free): Use it.
