In 32-bit more, the Core series ABIs use the x87 registers by
default.  You'll need to add -ffloat-store to the gcc options
used when compiling xLAMCH.  The options -march=native -msse3
-mfpmath=sse may work with recent enough versions of gcc.

If you're in 64-bit mode, then I don't know what's wrong.
