I presume you are using Hans Boehm's garbage collector? If so, did you
follow the instructions on:
http://www.hpl.hp.com/personal/Hans_Boehm/gc/simple_example.html
What platform are you developing for? If it is not Linux, you have to
make sure that GC_INIT() is being called before using any of the GC_xxx
functions.

Perhaps you can give us some more context. A simple, compilable example
would be great to see where and how exactly you are using your
redefinitions.
Best regards,
