rpmbuild: double free or corruption (fasttop)

Hello,

I don't know if I'm doing something wrong regarding a package which
includes file capabilities support or if I've hit a bug.

I've added libcap-devel as BuildRequires (probably it's already part of a
base system) and replaced the %attr tags in the file section (to remove
setuid) with a %caps directive.

The rpm builds and links fine as long as I don't use the %caps directive in
the file section. If I enable it, I got error "-6" when rpmbuild tries to
packs the rpm file after building:

So far I've tested this only on Fedora 18.

Any hints?
