Whoop! You are absolutely right, Dave, and in fact I think
this happened to me at one point too... my C compiler binaries
got corrupted due to -O optimizations and then produced bad code.
Maybe the gcc makefiles should be adjusted so that they will
never be built with higher optimization levels. Would that be
hard to do?
