[Bug fortran/38568] ICE with invalid bounds for I/O FMT= array



------- Comment #2 from fxcoudert at gcc dot gnu dot org  2009-03-29 08:35 -------
The testcase segfaults for me on current trunk on x86_64-linux, this is what
gdb says:

a.f90:3.14:

 WRITE(*, FMT(1:9) )  ! Invalid 1:9 is regarded as array bounds not at
substring
              1
Warning: Upper array reference at (1) is out of bounds (9 > 1) in dimension 1

Program received signal SIGSEGV, Segmentation fault.
