This quite likely means that the relevant bit of code has something which is classed as undefined behaviour in C/C++.

This leads me to believe that ports uses some non-default compiler

Compare the compiler commands printed when it builds?

Duh! Thanks for keeping me in check. Seems that ports adds a -O2 -pipe

to the compiler flags. -pipe itself is fine, but -O2 and above seems to

cause instability, so I set CFLAGS & CXXFLAGS to -O1 -pipe, things seem

AOK!

Thanks again Stuart, this was rather obvious- silly me.

Appreciated-
