I just tried the patch and it seem to work! thanks a lot
anyway I don't get your point about the realloc. Of course it works
with size=0, and what it does is that it probably frees() the
allocated vector.

from the realloc man:

"If size was equal to 0, either NULL or a pointer suitable to be
passed to free() is returned."

this means that if the return value of realloc is NULL then the
realloc just freed the memory, otherwise you have to do it by
yourself.
