It sounds like this is correct behavior, although I'm not quite sure of
exactly what you're asking.  If you mistype function names, then
necessarily things will not work -- it's not the compiler's job to figure
out what you might mean when you make a typo (and missing an underscore is
a typo), it's up to the programmer.

A non-existent function should result in the link phase failing.

One possibility is that you're using standard library functions (like
malloc/free in stdlib.h) without including the appropriate header.

I suspect there's something more fundamentally wrong with what you're
doing, but it's hard to guess without more information.
