Subject: 24.3.50; PUSH_HANDLER leaks memory?
Date: Mon, 04 Nov 2013 19:32:39 +0100
Hello.

While running leaks on OSX, it indicated that PUSH_HANDLER.  I can't find anywhere where
handlerlist members are freed.

Consider handlerlist = NULL.
One PUSH_HANDLER will then allocate one struct handler that becomes handlerlist, next is NULL and nextfree is NULL.

In the code, for example internal_condition_case_1, the code simply does
    handlerlist = handlerllist->next

thus loosing the allocated struct.  There must be a corresponding xfree somewhere but I can't find it.
