Oh! I've seen this before. The problem is you're running out of memory:

mmap() failed: Cannot allocate memory

Wine reserves a bunch of memory, and then STO is likely using lots of memory.
On top of that, Pulse tries to allocate 64 MB of memory, which is a lot. In
your particular arrangement, this allocation fails and shows the above message
and then crashes. None of this is really a "bug," per se, we've just run out of
32-bit address space.

You can work around this by asking Pulse to use less memory. In
</etc/pulse/daemon.conf>, see these lines:

; enable-shm = yes
; shm-size-bytes = 0 # setting this 0 will use the system-default, usually 64
MiB

In the past, we've recommended setting shm-size-bytes to 1048576. You can find
(mostly useless) descriptions of these options in the pulse-daemon.conf(5)
manpage.
