It's a bug in either gcc or recent versions of AIX's linker that 
manifests with static variables when debug symbols are enabled.

I suspect disabling debug symbols at build time would help:

CFLAGS="-O2" ./configure && make

but it's not been confirmed either way.

     Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
