Subject: Re: [hwloc-devel] hwloc-1.3.1 assertion failures on Linux/POWER7
From: Paul H. Hargrove (PHHargrove_at_[hidden])

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.
