Description

If the fpm testsuite is compiled with gfortran's -fcheck=all flag, several runtime allocation errors arise from the dependency checking testsuite:

# Testing: fpm_module_dependencies
# Starting library-module-use ... (1/15)
At line 819 of file /Users/federico/Documents/GitHub/fpm/src/fpm_targets.f90
Fortran runtime error: Allocatable actual argument 'model' is not allocated

Error termination. Backtrace:

The reason is that some routines e.g. add_target have non-allocated allocatable variables of model in non-optional dummy arguments:

fpm/src/fpm_targets.f90

Lines 247 to 251 in 5efb9e0

call add_target(targets,package=model%packages(j)%name,source = sources(i), &
type = FPM_TARGET_CPP_OBJECT, &
output_name = get_object_name(sources(i)), &
macros = model%packages(j)%macros, &
version = model%packages(j)%version)

fpm/src/fpm_targets.f90

Lines 400 to 408 in 5efb9e0

subroutine add_target(targets,package,type,output_name,source,link_libraries, macros, version)
type(build_target_ptr), allocatable, intent(inout) :: targets(:)
character(*), intent(in) :: package
integer, intent(in) :: type
character(*), intent(in) :: output_name
type(srcfile_t), intent(in), optional :: source
type(string_t), intent(in), optional :: link_libraries(:)
type(string_t), intent(in), optional :: macros(:)
character(*), intent(in), optional :: version

Expected Behaviour

Should not crash
