Subject: Fix for Mac OS X Garbage Collection Crashes

Message-ID: <m2pth2uhz5.fsf@owlbear.local> (raw)
If you've updated and built Emacs from CVS on OS X within the past few
weeks, you may have experienced crashes while Emacs is doing garbage
collection. The following patch, just checked into CVS, solves the
problem. I highly recommend updating to include it.
Index: darwin.h

The problem is caused by a change to src/alloc.c about a month ago that
causes garbage collection to crash under certain circumstances (when
LISP_INT values are on the gcprolist) if GC_MARK_STACK is set to
GC_USE_GCPROS_AS_BEFORE. The best way to fix the problem is probably to
fix the bug introduced. I don't want to work on that. Instead I have now
set GC_MARK_STACK to GC_MAKE_GCPROS_NOOPS. This option for GC has been
chosen on nearly all other platforms. So by following suit on OS X, we
may actually be using better-maintained code in the future. This is
probably a better solution.
