What tool produced that dump?  Do you have gdb available?
(a gdb backtrace means more to me than what you show).

You mention it's a reverse proxy, and the first thread you show is
a proxy request.  Are the crashes always associated with that,
so we could look there for a cause?  Or is that a meaningless
question because the server does nothing else?

You might also apply Jeff's APR patch at
https://issues.apache.org/bugzilla/attachment.cgi?id=24161
and see if that helps.
