How does std::string allocate memory in GCC with -fwhole-program?

Question

Update: The following problem appears to depend on the -fwhole-program option.

I\'ve been playing around a bit with memory allocation,

Answer 1

Looking at the output of g++ ... -S with / without -fwhole-program it appears that the whole custom new/delete operators aren't emitted at all when using fwhole-program.

I'm starting to suspect we're looking at a bug here.
