Thanks for answering guys. Yes José is right, hashing the pointer wasn’t even a good solution so I used another hash. I had the pointers stored in another data type and I wanted to quickly test for the their entry in the table but I found another way.

Hashing a value is interesting to reduce its compare time (taking collisions into account) and/or verify message integrity, and hashing a pointer does not meet none of this goals as it is process wide unique (no collisions) and its size is the fastest compare operation (most architectures).
