I accidentally under-reported the failures I saw w/ xlc.
In addition to the 2 assertion failures, I had the following SEGV's from 1.3.1:

/bin/sh: line 5:  6644 Segmentation fault      ${dir}$tst
FAIL: hwloc_bind

/bin/sh: line 5:  6676 Segmentation fault      ${dir}$tst
FAIL: hwloc_get_last_cpu_location

/bin/sh: line 5:  6768 Segmentation fault      ${dir}$tst
FAIL: hwloc_is_thissystem

Which matches Chris's report.
I think the assertion failure w/ 1.3.1 and gcc is an entirely different problem.

When running "make check" in hwloc-1.3.1 on a Linux/POWER7 system I see:
Doesn't seem to happen on Power6 (SLES10SP4) with GCC for hwloc 1.3.1 or
1.4.

With XLC and 1.3.1 and 1.4 I get plenty of warnings (compile logs for
both attached) whilst compiling and then 4 failures in make check
(accompanied with segmentation faults):
