Compiling these 2 routines in the same source file with gfortran -c
SUBROUTINE SUB1( str )
IMPLICIT NONE
CHARACTER(len=*) :: str(2)
CALL SUB2( str(1)(:3) )
END SUBROUTINE SUB1

with gfortran 4.6.1 on Fedora 15 (x64) and with MinGW on Win32.
The problem was also observed on 4.6.0 on Fedora 15 but was not seen on 4.5.x.
The ICE does not occur if any of these are true:
-fno-whole-file is used
The routines are in separate files
The str array is changed to a scalar
The str length is changed to a constant
