If I remember correctly (I have currently no such machine at hand), the size of int is 32 bit on amd64 (with gcc) and the size of void* is of course 64bit. Therefore the cast is wrong. It looks like the code is not 64 bit clean (at least not on AMD64 with gcc), because it makes some assumptions that are not always true.

Yes, this is exactly what is happening -- trying to store a 64-bit pointer in a 32-bit int. I was thinking about creating a C++ container to map a unique integer to the udata pointer.
