compiling stops in bootstraps stage

[Noah yan]

Not sure the following compling failure is for all or just my case.
That is from lates source base, but before that, my installworld did
not complete to the end. i suspect that partially installed world
causes the following error. appreciate if you have any hints or
comments on this.
