I tried different optimization flags, and "-finline-functions" seems
to trigger the bug.

I tried compiling gcc 3.0.3 with older compilers, and the bug happened
on both of the following cases:

  1) gcc 3.0.3 compiled with gcc 2.95.2 on mips-sgi-irix6.5
  2) gcc 3.0.3 compiled with egcs-2.91.66 on i686-pc-linux

Here are the corresponding outputs:

I also tried to compile Matrix.cc on my friend's machine with gcc
3.0.2 (Red Hat 7.1 on i386-redhat-linux), and it worked ok:
