instruction.  Valgrind does not currently support such instructions.  Sorry.
Illegal instruction

Any clue what is causing this?  i configured with:

./configure --enable-debug --disable-static --enable-plugin-builddir --disable-examples --disable-tests --disable-libmmx --disable-atomic

How do i turn off all optimizations?
