On OpenBSD 7.5/x86 (a VM built from
https://cdn.openbsd.org/pub/OpenBSD/7.5/i386/install75.iso ),
the 'gzip' executable crashes when compressing:

1) During the build:

$ make check
...
gmake  check-local
gmake[3]: Entering directory '/home/bruno/gzip-1.14.96-72fa/build'
  GEN      gzip.doc.gz
Segmentation fault (core dumped) 
gmake[3]: *** [Makefile:2200: gzip.doc.gz] Error 139

2) Invoked manually, under gdb:

Program received signal SIGSEGV, Segmentation fault.
longest_match () at match_.s:25


On other x86 platforms (Debian 12, Slackware 15, Alpine Linux 3.18,
FreeBSD 14.0, NetBSD 10.0, Solaris 11 OpenIndiana), it's fine. So,
the problem is definitely OpenBSD (or clang) specific.
