------- Comment #1 from burnus at gcc dot gnu dot org 2007-05-03 19:43 -------
==11966== Invalid read of size 8
==11966== at 0x41BF0C: gfc_check_pointer_assign (expr.c:2555)
==11966== by 0x4519D0: resolve_code (resolve.c:5225)

Better test case:
-------------------
character (len = 7), target :: textt
character (len = 7), pointer :: textp
character (len = 5), pointer :: textp2
textp => textt
textp2 => textt(1:5)
if(len(textp) /= 7) call abort()
if(len(textp2) /= 5) call abort()
textp = 'aaaaaaa'
textp2 = 'bbbbbbb'
if(textp /= 'bbbbbaa') call abort()
if(textp2 /= 'bbbbb') call abort()
end

Fixed in 4.3. Not for 4.2.0. If someone has strong feelings about 4.2.1, please
reopen.
