Fix this by reducing the fib/fib_wrapper argument from 23 to 22. Same for declare_target-2.f90. Tested on x86_64 with nvptx accelerator. libgomp/ChangeLog: 2022-01-27 Tom de Vries * testsuite/libgomp.fortran/examples-4/declare_target-1.f90: Reduce recursion depth. * testsuite/libgomp.fortran/examples-4/declare_target-2.f90: Same.
