Sorry about the delay in reply, I was moving and things were very
chaotic. Did you track down a specific place in the source where this
reuse of a variable triggered a problem?
TBH this sounds a lot like a compiler bug - have you tried compiling
the 64-bit version with all optimizations disabled? Also, is the test
suite passing? Sorry, I have a feeling I've asked this before but in
the intervening week+ I've been pretty distracted.
How are you checking the length of the p/q variables? Certainly
a 768 bit RSA key should have 48 byte p/q values in all cases.
