Re: Can realloc be marked as a mallloc-like function?

It looks like gcc assumes a functon marked with DECL_IS_MALLOC won't

for realloc. Now, the qestions are

1. Can gcc make such an assumption?
2. Can realloc be marked as DECL_IS_MALLOC.

BTW, glibc also marks realloc with __attribute_malloc__.

There was an absurdely long thread on this topic starting at <http://gcc.gnu.org/ml/gcc/2004-01/msg00005.html>. I didn't dig through it to find the answer.
