another rpm that causes rpm (tested on two different hosts) to crash.
the rpm is built similarily on carme: rpm-5.4.10-38.1.x86_64

carme rpm may be producing invalid rpm archive, but rpm binary should not crash on that!

also some characteristics of host where rpm's were produced. maybe it's relevant:

the filesystem is mounted with xfs 64bit inodes, so the inodes can be >2GiB signed integer

this will became more critical than just "don't build on carme"

19:17:26 glen> arekm: any chance you disable 64bit inode on carme? rpm is crashing and nobody is fixing the bug

:57:06 +arekm> glen: disabling requires recreating files and there is no tool on linux for that
