# gcc -m64 int_malloc.c
try -mcmodel=medium.
basically, mcmodel defaults to small in most cases, which means
32b data relocations. medium bumps single-object addressability
up to 64b. neither of these affect the basic addressing model
(int=32b, long=64b, pointer=64).
This is with a 2.6.5 kernel (SLES 9).
not a kernel issue, but rather the width of address calculations
for a single addressable object (as decided by the compiler.)
