Emacs seems awfully unstable on OS X lately

[Harald Hanche-Olsen]

Do other OS X users experience stability problems on OS X with recent
builds from trunk?

I built an emacs from current trunk on September 6. It had a tendency
to get stuck in garbage collection and needing to be killed,
especially when I tried sending emails with large-ish attachments (on
the order of a megabyte or two).

So I built a new one yesterday. It is even more unstable, just
crashing randomly in the main event loop.

So for the time being, I have reverted to a version that I build in
late July, which seems stable enough.

I am not sure that I have enough data to send a meaningful bug report.
Are the OS provided crash logs useful? I have read somewhere that gdb
doesn't work with the output of the current crop of Apple's compilers,
so I haven't even tried using that.

I'll try to gather more information on these crashes if needed, but
then I could use some tips on how to do it. But if others are seeing
these crashes and are actively working on fixing them, I'll just wait.
