Indeed, that would explain your observations. Perhaps either the front-end or some library it loads is one of the few programs that just doesn't work quite right with gcc-4.1 yet. Good detective work! So it would appear you have to try recompiling it with gcc-3.x again, and see if that eliminates the problem. If not, you'll have to check its dependency tree and try recompiling it. Get that 90% off the CPU and maybe you'll see the better general efficiency of gcc-4.1, regardless of whether you try my cflags or not. In fact, that's what I'd recommend you do, before trying my cflags. You'd then have a better base on which to measure whether my cflags made a difference for you or not, as opposed to what gcc-4.1.x itself did. -- Duncan - List replies preferred. No HTML msgs.
