Summary: Segmentation fault with assumed rank allocatable
intent(out) with bind(c)

Code demonstrating problems.
Hi all!
Segmentation fault both on:
GNU Fortran (GCC) 9.2.1 20191119
and
GNU Fortran (GCC) 10.0.0 20191119 (experimental)
Seems to be triggered by an erroneous call to free on entry (required by
intent(out) *if* allocated)
Heisenbug type does not trigger always, does not show under gdb or valgrind.
Compiling using the flag "-static-libgfortran" seems to stabilize it, crashing
repeatedly, also under gdb, but not under valgrind.
The flag "-Wmaybe-uninitialized" generates garbage diagnostics.
