--- Comment #1 from Zebediah Figura <z.figura12 at gmail.com> ---
Thanks. It's using some undocumented internal socket details.

As a side note, it's crashing on my main development machine, with an illegal
instruction. Disassembly shows it's trying to use the instruction

   14002185c:    c4 e2 f3 f6 c9           mulx   %rcx,%rcx,%rcx

which requires the BMI2 extension, which my processor don't have. I don't know
if this is a bug (i.e. if the program is supposed to detect a missing extension
on Windows), but either way it's hampering my development somewhat; is it
possible for you to provide an executable tuned for earlier CPUs?
