Hi folks,
Whilst trying to work out this "make check" error I'm seeing
on SLES10/PPC I ran the failing hwloc_bind test under Valgrind.
The first time around I missed the errors due to the number of
warnings about unsupported syscalls. :-(
There are 18 different error contexts reported, a lot more on
PPC than on this Intel x86-64 laptop.
This is the error on x86-64:
==13648== 6 errors in context 1 of 1:
==13648== Conditional jump or move depends on uninitialised value(s)
