I have come up with an even simpler reproducer:


$ cat test2.f90
subroutine test(string)
character(len=:), allocatable :: string
allocate(character(len=3) :: string)
end subroutine test
$ gfortran -c -fbounds-check test2.f90
test2.f90: In function ‘test’:
test2.f90:1:0: internal compiler error: in copy_to_mode_reg, at explow.c:635
