--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
realloc is not under GCC control.  That is GCC does not provide the libc where
realloc is implemented.

Please report this to where your libc is from.  I suspect either cygwin or
mingw.  But saying that can you double check to make sure you are not writing
past the memory allocation because if you are then realloc could possibility to
return NULL.
