Are there any C++ exceptions involved here? I have no idea
what might happen if the C++ runtime attempts to propagate
an exception through Pyrex or Python code.

Okay, send away.

If you can point out the places where you needed to add these
conversions, I could have a look at the generated C code in
the vicinity and see if anything looks wrong about it.
