Your system uses a buggy GCC-3.4!

When using this version to compile MCTDH, it will produce invalid code
when using SSE instructions for floating-point arithmetic. This is e.g.
the default on x86_64 systems (AMD64, EM64T).

Please consider one of the following:
- Upgrade GCC to at least 3.4.4; consider upgrading even to 4.1.1 or
  later, it produces much faster 64bit code.
- In install/compile.cnf, in section g77, remove the option "-mfpmath=sse"
  from MCTDH_FFLAGS_OPT. This is a slight performance penalty.
