After compiling it with the same xlc version, I found that pg_dump works as expected. So, the problem appears to be somewhere in the 9.1 source code, at least for binaries created from it for AIX (6.1).
Hm, maybe this 9.1.2 fix?

Avoid platform-dependent infinite loop in pg_dump.
If malloc(0) returns NULL, the binary search in findSecLabels() will
probably go into an infinite loop when there are no security labels,
because NULL-1 is greater than NULL after wraparound.
(We've seen this pathology before ... I wonder whether there's a way to
detect the class of bugs automatically?)
Diagnosis and patch by Steve Singer, cosmetic adjustments by me
