Well, any linux box with manpages >= 3.20 will have that latest text. Take debian's http://ftp.de.debian.org/debian/pool/main/m/manpages/manpages_3.25.orig.tar.gz for instance. > > > what is the correct fix for hurd then? > > > > This is precisely the correct fix: just using POSIX 2008's behavior, > > already available in glibc since ages. > > i hope those ages also cover the distros still shipping apparently old man > pages because otherwise this fix will introduce new bugs on other platforms > than hurd. The old manpages still do say that glibc allocates memory in that case, so it'll work there. They are saying it's not a good idea to rely on it because it's a glibc extension, but in my patch I'm precisely using it only with glibc, so it's completely fine.

No. That's one of the biggest mistakes of Posix. Samuel
