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.
