[gentoo-user] gcc fails and then succeeds - definitely a problem?

2012-02-23 Thread Grant

Parallel builds are not deterministic so if the Makefile allows a race condition to develop it's pot luck whether you'll be hit with it or not I got sick of stuff like that so I run MAKEOPTS=-j1 on all of my systems. If it were a frequent occurrence, there may be some benefit in that.
