Thank you for reporting this issue. could you rerun the tests with "--rerun failed --output-on-failure" to get more information on which tests are actually failing, please?

[jvdp1]

Could your issue be related with the PR #736 ?

[wpbonelli]

I see the same on macOS 13.6.1, aarch64-apple-darwin22.3.0, GCC 13.2.0. It is indeed the move test that fails, in particular move to self:

stdlib/test/string/test_string_intrinsic.f90

Line 717 in b8fbb3c

call move(from_string, from_string)

[jvdp1]

Thank you @wpbonelli for testing. This issue should have been solved with #736 . Question: is it an issue with the compiler or with the code?
As I don't have a macOS, could you investigate what the problem is, please?

[wpbonelli]

It may be related to apple silicon — @Pranavchiku has not reported arch but presumably CI would fail here if it was universal on mac. I will investigate.

edit: confirmed the test passes on an Intel Mac with gcc 13.2

[wpbonelli]

At this point it seems like a compiler problem. The issue does not reproduce in a minimal test https://github.com/wpbonelli/move-test on arm64. My next step is to add a test-drive harness and see if it still succeeds.

I guess I will try to systematically bring the test project to equivalence with stdlib_string_type.f90 to track it down

On Apple M1 Max with GFortran 11.3.0 I get:
