gcc/ChangeLog:
	PR sarif-replay/118792
	* libsarifreplay.cc (sarif_replayer::handle_region_object): Fix

gcc/testsuite/ChangeLog:
	PR sarif-replay/118792
	* sarif-replay.dg/2.1.0-valid/error-with-note.sarif: Update
	expected output to reflect fix to off-by-one error in handling of
	"endColumn" property.
	* sarif-replay.dg/2.1.0-valid/malloc-vs-local-4.c.sarif: Likewise.
	* sarif-replay.dg/2.1.0-valid/signal-1.c.moved.sarif: Likewise.
	* sarif-replay.dg/2.1.0-valid/signal-1.c.sarif: Likewise.
