Interesting. Could you update to the latest libzmq master, and build
with the debug flags (--with-debug when configuring the lib), and
would it be possible to set a break point on those lines and give us a
backtrace on the crashing machine, and take a look at the state of the
message? In gdb, that would be

gdb pgm_sub
break session_base.cpp:156
run all
<when it hits>
print *msg_

Not at all sure why msg flags would be set. I haven't got a 32 bit
build of anything at the moment by the look of it, but I'll try and
find one at some point!
