It seems as if gcc produces assembler code that as does net (yet)
understand.
I suggest to switch back to pentium3 for the package that fails; I think you
won't notice any difference in performance. If it happens to more packages
in base system, I suggest to compile the whole base system with pentium3.
IMHO P4 optimization makes only sense for applications that really _need_
the performance. If it makes too many troubles, the performace gain of less
than 1% for "normal" applications isn't worth the time you spend.
Greetings,
Alex
