Segmentation faults of bootstrap compiler?

[Ben Gamari]

Hello everyone,

Earlier this week there was a commit (perhaps
ef26182e2014b0a2a029ae466a4b121bf235e4e4) which appears to trigger
segmentation faults of the stage 0 compiler (GHC 8.2.1) during
validation on Harbormaster (e.g. [1]). Unfortunately I've been unable to
reproduce this reliably. Has anyone else observed this in their own
environment?

Cheers,

- Ben
