middle-end/101292 - invalid memory access with warning control
The warning control falls into the C++ trap of using a reference
to old hashtable contents for a put operation which can end up
re-allocating that before reading from the old freed referenced to
source. Fixed by introducing a temporary.

* diagnostic-spec.c (copy_warning): Make sure to not
reference old hashtable content on possible resize.
* warning-control.cc (copy_warning): Likewise.
