Well our digging took us full circle back to mono. 

We've tried building libc6 and mono with gcc 4.4 and 4.5! If it was a problem
with libc6 itself surely the entire system would be unstable?

Then we started trying to debug mono by attaching gdb to the mono instance
launched by monodevelop when soft-debugging and breaking inside the
debugger-agent related code. It did seem that the stack manipulation performed
during debugging is the likely culprit but with practically no understanding of
what is going on inside the mono run-time, we couldn't determine what part of
the code was responsible for throwing the stack out of alignment in this

It really needs someone who understands how the whole lot works and fits
together to be able to track down the cause, preferably running an i7 processor
so that they can see the same issue we're seeing.

We've been battling with this for 1.5 months now and the combination of
spending so much time trying to determine what the problem is and the actual
inability to debug has meant the game we were working on has been halted for
the entire time!
