PR c++/71184: Fix NULL dereference in cp_parser_operator
The source-range handling for the array form of operator
new/delete erroneously assumed that the "]" was present,
leading to a dereference of NULL when it's absent.
Fix it thusly.
gcc/cp/ChangeLog:
PR c++/71184
* parser.c (cp_parser_operator): For array new/delete, check that
cp_parser_require returned a non-NULL token before dereferencing
it.

PR c++/71184
* g++.dg/pr71184.C: New test case.
