fpm tests failing to run/compile

[banana-bred]

Description

Trying to package and compile fpm v0.12.0 with gfortran version 15.1.1 gives me the following backtrace (debug options added to compilation for the sake of this issue) when running fpm test in the fpm source folder:

==> Starting check()...
[  0%]        fpm_backend_console.f90

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Backtrace for this error:

I see that the binaries are built wth gfortran 12. Is this related ? Please let me know what other info I can provide.

Running fpm test with the linux binary from the 0.12.0 release, I get:

[ 98%] Compiling...
test/fpm_test/main.f90:49:34:

Thank you for reporting this @banana-bred - looks related to this issue with test-drive: https://github.com/fortran-lang/test-drive/issues/49

Yes, we don't build fpm with gfortran-15 yet but this issue needs to be addressed somehow.

This issue seems to be a bug in gfortran-15 when using -Wall which adds an option for extra interface checks rather than warnings.
