Tom de Vries 4a57a4b629 [openacc, testsuite] Fix undefined behaviour in atomic_capture-1.f90 
2018-04-28  Tom de Vries  <tom@codesourcery.com>

	PR testsuite/85527
	* testsuite/libgomp.oacc-fortran/atomic_capture-1.f90 (main): Store
	atomic capture results obtained in parallel loop to an array, instead of
	to a scalar.
