Ah. That's the bit of information I was missing. If the ABI changes,
it's a wonder my hacking of my extension to build in debug mode worked
at all!

I suspect that if I could get distutils to let me specify that it
keeps debug symbols in a release-mode build, I could get what I
needed. But the arcane contortions needed to get distutils to do this
are beyond me :-)

I'll stick with printf - it's served me well enough so far :-)

Thanks for clarifying,
