Is it g++ causing the segfault? To me looks like so... I can think of two reasons for the bug then:

Excessive memory allocation (because of the pipe flag, you whould try disabling it)
Yet another pch problem, try paxmarking gcc and removing RANDMMAP if it works then it's probably that.

[Comment 2 Michał Górny 2012-06-26 03:59:53 UTC]

The ICE seems to happen in g++ headers, so I don't know what we can do about it.

need an actual log attached here

if it's pch related, not anything new on that front afaik

It shouldn't be since we now set paxctl -r on gcc's components.  See lines 1585-1586 of toolchain.eclass and bug #301299
