This patch fixes a segfault in libgomp.oacc-fortran/non-scalar-data.f90. The problem here is that 'n' is a parameter, and the kernels region implicitly adds a copy clause to n. Naturally, the test segfaults when it comes time to write the value back to the host as the kernels region terminates. This problem only occurs on nvptx targets.
I'll apply this patch to trunk as obvious. Cesar
