Build failures and test suite failures with gfortran 15.1
Caffeine currently fails to build with the newly released gfortran 15.1.0
Initially the problem is build errors in the GASNet dependent library, but these can be bypassed by setting CFLAGS=-Wno-incompatible-pointer-types before install.sh.
That workaround setting is sufficient for me to fully build Caffeine, but the test suite fails at runtime, with what might be a Veggies defect.
Here is output from Caffeine fpm test:
[100%] Project compiled successfully.

@bonachea It looks like the test suite doesn't fail at runtime, but that when compiling the tests, the seg fault happens. Is that true?
Do you have gfortran-15 installed locally? Or did you discover this in CI? If you have it locally, could you run a different veggies test suite, maybe even the test suite of veggies itself, with gfortran-15?

No, if you look at the first two lines in my output snippet you'll see this is definitely after the test executable has finished building and started executing.
The crash happens early inside our call veggies::run_tests(). It apparently crashes while gathering up the textual display of tests it plans to run. I've confirmed via debugger that the crash occurs before the first test code runs (and hence before the first call to prif_init).
We have gfortran 15.1 installed on our internal Linux cluster and I've been poking it there. I have not yet tried running any other non-Caffeine Veggies tests.
The self-check test suite for Veggies v1.1.3 (which is what Caffeine currently uses) crashes in a similar way:
[100%] veggies-test done.
[100%] Project compiled successfully.

Using the tip of veggies:main I also get a similar result:
[100%] veggies-test done.
[100%] Project compiled successfully.

So this defect is definitely independent of Caffeine and also occurs in the latest Veggies.
@bonachea Okay, thanks, so it is runtime. Also, thanks for checking with the test suite of Veggies. One of us should open a bug report on the Veggies repo. Let me know if you are too busy and want me to use the above messages to open it myself.
