Please attach the reproducer spec as well. (I assume this is reproducable?)

It's not a standard spec, in fact it's an opensuse one.

Should I still have to upload it?
Comment 12 Panu Matilainen 2013-04-16 03:46:14 UTC 
How is a spec from Suse not a standard? If rpm crashes on one of those, it can crash on a Fedora spec too. So yes, please attach the spec especially if the crash is indeed reproducable with it.

Please see the attachment.

Thanks.

Easily reproduced now, will fix. Thanks for reporting.

Could you tell me the details?

Thanks.
Comment 16 Panu Matilainen 2013-04-17 07:12:44 UTC 
When I know what the details are :)

Its related to the %{apache_libexec} and %{apache_sysconfdir} macros which fail to evaluate as %{apxs} is not defined (and in the original spec, apxs path is wrong). This blows up something in the files list processing / dependency generation.

For now, "%define apxs /usr/bin/apxs" should allow the package to be correctly built.
Comment 17 Panu Matilainen 2013-04-17 11:09:24 UTC 
The problem is these %files entries:

%dir %{apache_sysconfdir}/../conf.d
%config (noreplace) %{apache_sysconfdir}/../conf.d/w3perl.conf

When %{apache_sysconfdir} evaluates to nothing (as is the case with the reproducer spec), the paths end up being:
/../conf.d
/../conf.d/w3perl.conf

Rpm thinks these are ok as they start with /, but they actually "escape" the buildroot and the dependency generation blows up because it assumes all paths are inside the buildroot. So the crash is actually just a symptom of a more fundamental (and ages old) flaw: its trivial to escape the buildroot in %files, whether by accident as happens here, or on purpose.

Fixed upstream now:

Fixed in rpm >= 4.11.1:
