New Revision: 242025

URL: https://gcc.gnu.org/viewcvs?rev=242025&root=gcc&view=rev
Log:
	* libstdc++-v3/include/bits/regex.h (regex_iterator::regex_iterator()):
	Define end() as _M_pregex == nullptr.
	* libstdc++-v3/include/bits/regex.tcc (regex_iterator::operator==(),
	regex_iterator::operator++()): Fix operator==() and operator++() to
	look at null-ness of _M_pregex on both sides.
	* testsuite/28_regex/regression.cc: New testcase.
