[Bug c++/34222] New: ice for legal code with -O3

[dcb314 at hotmail dot com]

Hello there,

I just tried to compile the Suse Linux package celestia-1.4.1-16
with the GNU C++ compiler version 4.3 snapshot 20071123

The compiler said

3dsread.cpp: In function 'Mat4f readMeshMatrix(std::ifstream&, int)':
3dsread.cpp:275: error: missing definition
for SSA_NAME: SMT.659_346 in statement:
SMT.659_363 = PHI <SMT.659_346(5), SMT.659_338(3)>
PHI argument
SMT.659_346
for PHI node
SMT.659_363 = PHI <SMT.659_346(5), SMT.659_338(3)>
3dsread.cpp:275: internal compiler error: verify_ssa failed
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

Source code attached. Flag -O3 required.
