Memory counters give segfault when attempting to use thread wild cards or numbers only total works

some other counters also don't work see objects and stack recycles

With reagrds to the first error you're reporting, I'm seeing this error message:

{what}: couldn't create performance counter: /runtime{locality#0/worker-thread#0}/memory/resident \
    (HPX(bad_parameter)): HPX(bad_parameter)

which is describing the reason for the stop: the counter does not exist.

These segfaults are a result of a stack overflow.

Stack back traces are now collected on a larger stack which fixes the issue (see f1bffea)
