Markus Armbruster d9d3aaea0b replay: Fix dangling location bug in replay_configure() ...

replay_configure() pushes and pops a Location with automatic storage
duration.  Except it fails to pop when -icount parameter "rr" isn't
given.  cur_loc then points to unused stack space, and will most
likely get clobbered in short order.

Clobbered cur_loc can make loc_pop() and error_print_loc() crash or
report bogus locations.

Broken in commit 890ad55.

I didn't take the time to find a reproducer.
