[Bug c++/30840] New: ice for legal code with flags -O3 -fno-strict-aliasing

[dcb314 at hotmail dot com]

I just tried to compile Suse Linux package rxvt-unicode-8.1-3
with the GNU C++ compiler version 4.3 snapshot 20070216.

The compiler said

screen.C: In member function 'void rxvt_term::scr_reset()':
screen.C:160: internal compiler error: in set_lattice_value, at
tree-ssa-ccp.c:487
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

Preprocessed source code attached. Flags -O3 -fno-strict-aliasing required.
