Yes, I know the current is svn 10755, but 43-45 don't matter and  the rest haven't been merged into the asio branch

Sure.
Hm. That's an UDP crash, and UDP is not used in EC.

Tried a possible fix (recreating the UDP socket after an error) - 10757

Happened again - trigger this time was a router crash (locked up, no reboot, no offsite networking)

Was there no message before the "backtrace follows" ?
Can you try to run it with GDB for a proper backtrace?

Only the generic failure message. Nothing logged.

I'll try it inside gdb

Hmmmmmmmmmm....

With --enable-debug --disable-optimize (so that GDB can work) it's nice and stable.

GDB can work with --enable-optimize too. Maybe you can't see some local variables or so, but in general it should work.

It does - but it's still "nice and stable" when run inside the debugger.

Probably outside too. What you described appears to be triggered by some external events (like the router crash), unless that happens again you can't reproduce it apparently.
