I got a segmentation fault in Emacs. I read my email with VM (Viewmail), and I had a few fairly large mailboxes open when Emacs crashed. I had a few other cases where it crashed under similar circumstances, but other cases where it ran without problems.

I have the crashed instance under gdb, and I will keep it some time there to be able to extract more info. For the time being it looks like it is in the garbage collector.

The backtrace is very large, so it could be a stack overflow.

The 'bt full' output ran out of the buffer space in MacOS's Terminal window, so I have only the bottom part, but it seems to top part is mostly the same. And gdb got an error, so I cannot get more info out of it.
