Subject: 23.0.60; Crash during opening a large .tar.gz file
Date: Sun, 05 Oct 2008 13:37:45 +0900
Message-ID: <7zzlljzmg6.fsf@yfb02119.nifty.com>

Emacs crashes when I try to open a large .tar.gz file, in this case it's
`w3m-0.5.2.tar.gz'.  Emacs crashes during opening a large zip file, too.

I use today's cvs head, on below platform:
* Windows XP Professional Ver 5.1 Build 2600 Service Pack 3
* build by cygwin/gcc3 "-gdwarf-2 -g3 -mno-cygwin -mtune=pentium4 -O2"

Below is the output from `bt full' and `xbacktrace'.
