This is unrelated to GDB. It seems you have compiled the binary on
a different system than you run the binary. Compatibility is only backwards,
not forwards. You can run on newer system a binary that was built on older
system but not vice versa.
You can compare on both systems ZLIB_* versioning tags:
readelf -s /lib/libz.so.1 | grep ZLIB_
Now, my system is Fedora 12 and my suspicion is that GDB compiles
assuming a library version that is higher than what my system has.
/lib64/libz.so.1: no version information available
https://bugzilla.redhat.com/show_bug.cgi?id=557651
Fedora 14 had the version tag added.
I wanted to know where inside the GDB source code could I get information
about version information.
Not in GDB, GDB just asks for a symbol name (without the ZLIB_* version).
Linker adds the ZLIB_* requirement if system zlib has such version tag.
