Description Olivier Benghozi 2001-10-19 11:45:19 EDT
Just updated from glibc 2.2-12 (Errata RPM) to 2.2.4-18.7.0 (Newest Errata 
Some programs now coredump, like the last nmap (2.54b30), even if 
recompiled under this new glibc. Returned under old Errata RPM, recompiled 
nmap, it no longer coredumps.
Comment 1 Olivier Benghozi 2001-10-19 11:47:47 EDT
Just in case: IPV6 kernel module is loaded.
Comment 2 Jakub Jelinek 2001-10-19 12:08:39 EDT
You should never use IPv6 in 2.2 kernels. Either upgrade to 2.4 kernel,
or no IPv6. IPv6 is broken a lot in 2.2.
Or was this under 2.4 kernel?
Comment 3 Olivier Benghozi 2001-10-19 12:31:47 EDT
If I understand you, RedHat has done a mistake by including IPv6 tools in 
RedHat 7.0 with Kernel 2.2.x (traceroute6, ping6)...

Anyway, it is a 2.2.19 kernel; but nmap doesn't know about ipv6. So, are you 
sure that without ipv6 module loaded, nmap won't coredump with these glibc ?

Because this is a busy computer, and I would like to avoid rebooting if 
It doesn't use ipv6 actually, the module is loaded but cannot be unloaded 
without rebooting.
Comment 4 Olivier Benghozi 2001-10-19 19:43:20 EDT
... tested on another RH 7.0 WITHOUT ipv6: exactly the same thing.
Binary compiled and ran under new glibc: coredump.
Binary compiled and ran under previous glibc: ok.
Comment 5 Ulrich Drepper 2003-04-21 22:15:42 EDT
This bug is against a very old glibc version.  I doubt there is any point
keeping it open.  Support for this code is long gone and all new releases,e
specially RHL9, should have no such problem.
