[GSAS-II] Cancelling refinements crashes

[Ivo Alxneit]

Dear all

I get quite reproducible crashes (once in a while it does NOT crash)
when I try to cancel (click the cancel-button) a running refinement.

$ uname -srm

Valgrind gives me the following (Bad permission ...) which is probably a
stray pointer.
