Bug ID: 109983
Summary: [12/13/14 regression] Wireshark compilation hangs with
-O2 -fipa-pta
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ipa
Assignee: unassigned at gcc dot gnu.org

packet-rnsap.c.i.xz
Originally reported downstream in Gentoo at https://bugs.gentoo.org/907182.
Building Wireshark with -fipa-pta ends up hanging when compiling
packet-rnsap.c.
It's enough to just try to build the reproducer with -O2 -fipa-pta for me
(actually, -O1 hangs too):
```
$ gcc-12 -O2 -fipa-pta -c packet-rnsap.c.i
[... hangs ...]
```
gcc 11.3.1 20230518 doesn't hang, while 12.3.1 20230519 / 13.1.1 20230520 /
14.0.0 20230521 do.
