If I take the link line generated for -shared-libgcc and substitute the
the static libgcc, the resulting xplor binary doesn't abort on the throw.
Also if I take the link line generated without -shared-libgcc and add
"-lgcc_s.10.4", the resulting xplor binary also doesn't abort on the
throw. Anything else to try to help pin this down?
