The error-producing command line is
g++ -Wall -O3 -march=native -c videospeed.cc
videospeed.cc: In function 'int main(int, char**)':
videospeed.cc:275: internal compiler error: in expand_simple_binop, at
optabs.c:1158
Adding -save-temps gives a new warning "SSE instruction set disabled, using 387
arithmetics", and the compile succeeds. Also, changing to -march=i386 or
-march=i686 avoids the problem.
I will attach the g++ -E output, which does trigger the error.
