Subject: 2.5.50-ac1 mpparse -> gcc 3.0.1 segfault

Hello,
The machine I'm working on has SMP enabled (dual 2GHZ P4 Xeon), although
I've tried it on a different box with dual P3s and it's still a no go. It
didn't happen on 2.5.50-vanilla, so far as I can tell (it had other compile
errors wrt intermezzo, but it got past mpparse). Attached at the bottom is
the make output. Any info on similar occurrences or a fix would be
appreciated.

Thanks,

You need gcc 3.1.x to build 2.5.5x - you hit a compiler bug. With later
3.0.x you hit more insidious bugs in the compiler. 3.1.x/3.2 should be
fine

3.0.1 is now quite old, and has a number of issues. Try a more recent gcc,
and if the problem is repeatable, file a bug with the gcc folks, as the
output told you to.
