The interesting point is, that if I step into reallocmem, GDB can 
display the correct stackframe.

But FPC skips one frame. And the strange thing is: FPC includes the 
frame (the address in the frame) that does not have the full stackframe 
code (push... / leave). But it excludes the frame that called this 
optimised frame.
