I am getting a segfault when assigning one APFloat to another, as in: APFloat APF1(APFloat::IEEEdouble()); APFloat APF2 = APF1;

Just tried it; seems to work fine.

APFloat is a wrapper class that wraps either an IEEEFloat or a DoubleAPFloat. A union called Storage in APFloat contains the underlying object, which is one of those two types. The assignment APF2 = APF1

What assignment?  "APFloat APF2 = APF1;" calls the copy constructor, not the assignment operator.
