BUG/MINOR: http: Missing calloc return value check while parsing redirect rule
A memory allocation failure happening in http_parse_redirect_rule when
trying to allocate a redirect_rule structure would have resulted in a
crash. This function is only called during configuration parsing.
It was raised in GitHub issue #1233.
It could be backported to all stable branches.
