The multiplication with the sizeof the base type may overflow, esp.
on 32-bit machines with very large datasets, causing the function to

FIX MemoryError raising in trees (+test)
...
I got this wrong all along: Cython functions that don't return Python
objects need an "except" clause to actually propagate exceptions (spotted
by @GaelVaroquaux, @arjoly).
Simplified memory management and unified error messages by safe_realloc.
