bug#752: Freezes in 22


From: David Reitter
Subject: bug#752: Freezes in 22
Date: Wed, 20 Aug 2008 14:03:51 -0400

We've been experiencing freezes in Emacs 22 (Carbon, off CVS, patched).

The user supplied a stack trace (below), but he's running from binaries.

Is there anything else I can do to investigate this?

Subject: [Aquamacs-bugs] Freezes with nightlies

I've been running nightly builds for a couple days, and they seem to
be extremely prone to mysterious hangs. It seems like they deadlock
when multitasking. For example, I was connecting with ERC while I was
entering a command in the minibuffer, and Aquamacs froze when I hit tab.

Is this a known issue? Standard behavior for the nightlies?
