Subject: bug#2099: 23.0.60; `mark_object' with larger nested objects crashes Emacs
Date: Thu, 29 Jan 2009 00:06:45 +0100 (CET) [thread overview]
Message-ID: <20090128230645.07F1DC468CC@mt-computer.local> (raw)
When you do:
$ emacs -Q --eval "(let (v) (while t (setq v (cons v v))))"
then Emacs crashes with:
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0xbf7ffffc

Throwing an error or making GC stackless seems much preferable here.
