Description

Right now my branch fails evaluation with this delight:

hydra-eval-jobs returned exit code 1:
GC Warning: Failed to expand heap by 9999998976 bytes
Can't start up: not enough memory

I don't think I'm doing anything particularly unusual in it so it seems like a bug.

Research direction

Start by reproducing the evaluation failure from the linked Hydra jobset branch and review the hydra-eval-jobs output showing the heap-expansion and memory errors. Trace the evaluation path involved in that job and determine whether the failure is reproducible outside this branch. Done means the cause is identified and the affected evaluation completes without the reported memory failure.
