Segmentation fault - invalid memory reference with gcc

[nimgould]

If I compile and run with gfortran 6 and HWLOC enabled, I get the following segfault:

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Backtrace for this error:

#0  0x146c00115ea7 in ???

The offending line appears to be
if(obj->type == type) return 1;
in the private count_type function.

This happens for a variety of examples. I don't recall this with earlier versions of hwloc.
