-Subject: [PATCH] fix missing integer overflow checks in regexec buffer size
- computations
-
-most of the possible overflows were already ruled out in practice by
-regcomp having already succeeded performing larger allocations.
-however at least the num_states*num_tags multiplication can clearly
-overflow in practice. for safety, check them all, and use the proper
-type, size_t, rather than int.
-
-also improve comments, use calloc in place of malloc+memset, and
-remove bogus casts.

-Upstream-Status: Backport
