Yep, I've updated to 3.4.0 in the mean time, didn't realise I'd got out of date.

I'd love to be up to date but I'm one of the suckers that brought a 32bit Intel iMac.
We do still get the odd security update though, just no OS updates. At least we
still get Firefox and Chrome updates.

Yes it is, as soon as it was obvious that its wasn't an issue with code generation, I thought
trying it with llvm code generation might yield different results.

I've never managed to get the debugger to work to be honest. I usually do some sneaky debugging on the Win 7 work laptop
when debug prints don't do the trick. Of course I'm also stuck with Monodevelop 4 on the creaky old iMac :-)
