I've built and installed zlib-1.2.9 on my system (home rolled but based on Linux From Scratch). I've found that rpms created with this system cannot be installed. Nor can their contents be viewed with Midnight Commander (mc).
The error produced by rpm is:
[chris:~/rpm]$ sudo rpm -i x86_64/whois-5.2.14-1.x86_64.rpm
error: unpacking of archive failed on file /usr/bin/whois;586aad21: cpio: read failed - No such file or directory
error: whois-5.2.14-1.x86_64: install failed
When trying to view an rpm with mc a dialogue box pops up containing the message "Premature end of cpio archive".
If I revert to zlib-1.2.8 and rebuild the rpms, everything is OK, although rpms built when zlib-1.2.9 was installed still cannot be installed.
This table summarises what I have found:
BUILD INSTALL RESULT
1.2.8 1.2.8 GOOD
1.2.8 1.2.9 GOOD
1.2.9 1.2.8 FAIL
1.2.9 1.2.9 FAIL
I've bisected the problem and that ended with:
[chris:~/build/zlib]$ git bisect bad
4f1df00 is the first bad commit

Unfortunately, this commit does not revert because of subsequent commits, so I haven't tried that.
