[Llvm-bgq-discuss] Problems with binaries compiled with anything else than -O0

[Biddiscombe, John A.]

Hal,

Simple serialize test works fine (unfortunately, sort of - cos it’d make
debug much easier if it failed too).

One notable thing is that when I compiled with gcc 4.8.2 in release mode
it also dies in a similar place on startup inside boost serialisation code.

I’ll revisit this tomorrow hopefully

JB
