Hello,
expanding $reply_address on a mail with empty Reply-To and no From
segfaults. Here is a patch to fix that. According to the documentation,
setting *newsize back to 0 should be ok. Philip, please have a look if
this is really ok or if newsize should be saved and restored.
After finding out that Reply-To is empty, s is "" and newsize is 2.
Now find_header returns NULL, because From is not set, but newsize is
still 2, although a pointer to the statically allocated "" is returned.
Michael
