BUG(?): f2py selectedrealkind test failure on macOS-arm64 #21765
Description
Describe the issue:
In 1.23.0rc3 (built locally or pip-installed) and 1.24.0dev built on macOS 12.4/M1 (aarch64) test_kind is failing (everything else passing!) on
for i in range(20):
> assert selectedrealkind(i) == selected_real_kind(
i
), f"selectedrealkind({i}): expected {selected_real_kind(i)!r} but got {selectedrealkind(i)!r}"
E AssertionError: selectedrealkind(16): expected 10 but got -1
E assert -1 == 10
E + where -1 = <fortran function selectedrealkind>(16)
E + and 10 = selected_real_kind(16)Modifying the test to parametrise i confirms that the kinds differ for all values 16-20

Using built-in specs.
