Got a query about this bug...   
   
It is still valid for gcc 3.3.4   
My computer has been upgraded to a athlon-xp, so I tested both   
   
g++ -Os -march=pentium3 matrix.cpp -o matrix   
 and   
g++ -Os -march=athlon-xp matrix.cpp -o matrix   
   
they both gives Segmentation fault when running   
./matrix   
   
Other optimization levels works.  
   
Updated summary etc.
