It's possible your program corrupts some state used by the normal
malloc(), but a different malloc() (such as Valgrind's) doesn't get
corrupted.  If you can find a different malloc() implementation and link
with that (even dynamically with the LD_PRELOAD variable -- see the
'ld.so' man page for details) you might get a different result to the
normal malloc(), which would confirm (I think?) this hypothesis.
