--- Comment #18 from howarth at bromo dot med.uc.edu --- (In reply to howarth from comment #17) > Bug 65550 may be a duplicate of this one. Like Bug 65550, the random ICEs in pch.exp are suppressed by building gcc trunk with --enable-checking=release. In an unrelated issue, I see the parallel make for this test randomly hang for both the stock build and --enable-checking=release. I suspect that the pch.exp test harness isn't really parallel safe.
