In this case, I have found the bug consistently repeatable on multiple machines, all running snow leopard up-to-date. When built on my desk-top machine there were no other applications running except for "TeamViewer" (I built it from work). The other builds were made without TeamViewer. Browsers on/off, doesn't matter. I *have* a build that works -- I built it with gcc-4.4.3 with no problem. The difficulty is with Apple's gcc distribution. As I pointed out earlier, I'd be struggling if I didn't have a new version of gcc on-board. The only thing I did not try is to see if I used a gcc-4.5.0 build with --disable-bootstrap from Apple's gcc to rebuild gcc-4.5.0 with itself... Even then, I'd be somewhat worried that the then consistent compiler might be producing code at variance with builds on other operating systems yielding inexplicable bugs or bugs that other people could not reproduce on their platforms.
