Before this gets backported, the testcase should be fixed.  It uses an
incorrect declaration of realloc, assuming that size_t is long.  The standa=
rd
defines realloc as size_t, so the declaration should use __SIZE_TYPE__ inst=
ead.
 This works, although you could also just include stdlib.h or use
__builtin_realloc.=
