It won't. The mentioned problem is caused by clobbered registers in the 
MMX/SSE assembly optimizations in the synthesis algorithms. But it's actually 
not a bug in LS but a problem with some GCC versions. So you either have to 
upgrade your GCC to a more recent version (3.3.x should be sufficient) or 
disable the MMX/SSE optimizations in LS at compile time.

And as said, the usual compilation procedure for using CVS versions is

 make -f Makefile.cvs && ./configure && make

This accounts to all libraries and applications from the LinuxSampler project.
