Comment (by thomie):

 We're unlikely to put a lot of time in to investigate this bug, since you
 seem to be the only one running into it, and the current build system is
 being retired.

 Could you please try https://github.com/snowleopard/hadrian, and see if
 you can reproduce the problem.

 Please provide the following details:
 * which OS
 * which command do you run? (`make -j<N>`)
 * is there anything "weird" about your system. Slow disk?
 * after the failure, does the build continue successfully if you run
 `make` again?
