% gfortran --static test.f90
% a.out
oops
Abort (core dumped)
% cat test.f90
module foo
integer, dimension(:), allocatable :: bar
end module
program main
use foo
allocate (bar(100))
call init
end program main
subroutine init
use foo
if (.not.allocated(bar)) then
print *, 'oops'
call abort
endif
end subroutine init
=====================================
And here is the dump-tree-original, which clearly shows the problem:
init ()
{
extern struct array1_int4 bar;
bar.data = 0B; <<<<<<<<<<<<<<<<< ALLOCATION IS LOST HERE
if (bar.data != 0B == 0)
{
_gfortran_filename = "test.f90";
_gfortran_line = 14;
_gfortran_ioparm.unit = 6;
_gfortran_ioparm.list_format = 1;
_gfortran_st_write ();
_gfortran_transfer_character ("oops", 4);
_gfortran_st_write_done ();
_gfortran_abort ();
}
