Can it be that the build machine somehow used too many threads?  This is
just a hunch, but can we maybe test the build with -j1?  Maybe with many
CPUs it uses much more RAM or one process tries to use more than 4G ram
which is not OK on i686.

Any other tips what should I try locally to reproduce this issue?

Also, the error is consistently happening, but always at a different
point in the build process, so it is really strange.

On the other hand, the end result (haskell missing from bincache) is
really annoying :(
