I have on Linux/x86-64 these passes - which means all of them pass:
XPASS: gfortran.dg/ret_pointer_1.f90  -O0  execution test
XPASS: gfortran.dg/ret_pointer_1.f90  -O1  execution test
XPASS: gfortran.dg/ret_pointer_1.f90  -O2  execution test
XPASS: gfortran.dg/ret_pointer_1.f90  -O3 -fomit-frame-pointer  execution test
XPASS: gfortran.dg/ret_pointer_1.f90  -O3 -fomit-frame-pointer -funroll-loops  e
xecution test
XPASS: gfortran.dg/ret_pointer_1.f90  -O3 -fomit-frame-pointer -funroll-all-loop
s -finline-functions  execution test
XPASS: gfortran.dg/ret_pointer_1.f90  -O3 -g  execution test
XPASS: gfortran.dg/ret_pointer_1.f90  -Os  execution test

On Linux/i686 I get less passes:
XPASS: gfortran.dg/ret_pointer_1.f90  -O0  execution test
XPASS: gfortran.dg/ret_pointer_1.f90  -O1  execution test
XPASS: gfortran.dg/ret_pointer_1.f90  -O3 -fomit-frame-pointer  execution test
XPASS: gfortran.dg/ret_pointer_1.f90  -O3 -fomit-frame-pointer -funroll-loops 
execution test
XPASS: gfortran.dg/ret_pointer_1.f90  -O3 -fomit-frame-pointer
-funroll-all-loops -finline-functions  execution test

So, -Os and -O2 are broken on i686.

This is not fixed. 
It still fails for me at -O2 in i686-linux.

Andrew,

This one is fixed now, isn't it?  It runs fine with the CVS of 20041205
