MT crashes
|

I've been getting segfaults in MT versions recently.
Here's some output from a build with current source.
(You'll see that I find myself in the debugger with two
different threads at the same time, which is pretty
confusing.)
Since it shows some backtrace info, I'm hoping it will
be of some use without the source that caused it to happen.
I hope to send a small reproducible example, but it's going
to take a while.
