It surprises you that returning an uninitialized pointer value will
crash the code that tries to use the pointer?
I strongly recommend using a compiler that will warn about uninitialized
values. If using gcc, you should use -O1 (at least).
I dunno what the original problem was, but maybe you just neglected to
recompile the function against 7.4 headers? We don't generally
guarantee binary compatibility of user-defined functions across major
releases.
