Do you have a better memory? I think it is after 4.4 (so nothing can be infered from building 4.4.x). > In this case, I have found the bug consistently repeatable on multiple > machines, all running snow leopard up-to-date.

Can you (1) check that your builds fail as reported in comment #13 (you have to check stageX-x86_64-apple-darwin10/YYY/libgomp/config.log with X in 2 or 3 and YYY in . or i386 assuming you build for x86_64-apple-darwin10)? (2) provide your full configure line? > 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.

In my builds stage1 use Apple stock gcc: gcc version 4.2.1 (Apple Inc. build 5659). The only way I know that can convince anybody that the build is sane is to run make check for 32 and 64 bit modes (though it's certainly not a proof!-). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43170
