But I am quite sure that it failed for me. You could always do some re-runs of those tests using an older seed stage built against libmpc.so.1.

The gcc produced in the stage1 is broken, so won't run to rebuild itself during the stage2 run. Also the "--rebuild-if-new-ver gcc" only rebuilds gcc if it's deps are updated to new versions (likely breaking lib linkage), it is not unconditional. It is not as accurate as subslots, so may rebuild more often than possibly needed. But it is better than having unreliable stage builds, not knowing when they may break. -- Brian Dolbec

The best solution to this is, and has always been, just updating gcc's deps during update_seed. Or am I misremembering something? As far as I know, you don't need to waste time rebuilding the seed stage's gcc, since gcc is rebuilt in stage2 and then everything is built by it in stage3.
