[LLVMdev] Assert with getZExtValue()?

[Ryan Taylor]

Was hoping it might get some help or a better explanation of this:

/ADT/APInt.h:1217: uint64_t llvm::APInt::getZExtValue() const: Assertion
`getActiveBits() <= 64 && "Too many bits for uint64_t"' failed.

Program received signal SIGABRT, Aborted.
0x00007ffff6eb4d05 in raise (sig=6) at

#10 0x0000000000525509 in main ()

Also, why does it give <value optimized out>, when I print the value I
clearly get one, unless this is some result of const prop?

Thanks.
