Subject: glibc 2.36 build failure on Fedora 36 with gcc 12 (-Werror=use-after-free)
Date: Fri, 29 Jul 2022 11:26:04 -0400 [thread overview]
Message-ID: <ba9bccae-17db-0133-9361-c22582604eed@redhat.com> (raw)
Just posting here for the record that I see a glibc 2.36 build failure
with Fedora 36 and gcc 12.
localealias.c: In function ‘read_alias_file’:
localealias.c:335:56: error: pointer may be used after ‘realloc’ [-Werror=use-after-free]
335 | map[i].alias += new_pool - string_space;
| ~~~~~~~~~^~~~~~~~~~~~~~
localealias.c:325:49: note: call to ‘realloc’ here
325 | char *new_pool = (char *) realloc (string_space, new_size);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
I'm going to review this quickly before we make the glibc release.

Cheers,
Carlos.
