Hello world,
after Paul's fix for allocate on assignment (thanks Paul!), here is a
patch for the original test case from PR 22572, where the bounds of
the function are unknown at compile time. This uses an allocatable
temporary.
In the long run, another option is to use interface mapping to evaluate
the bounds of intrinsics and explicit-shape functions. For this, it
would be necessary to write a front-end-only version of gfc_evaluate_now, which
would be complicated by the desire not to disturb common function elimination,
so I've put that on the back burner for now.
Regression-tested. OK for trunk?
Thomas
