This code Cliff.roc.gz passed roc check/test on nightly-2026-09-18-1d982dc
Since upgrading to nightly-2026-10-04-130536d roc check/test is now throwing:
thread 457108 panic: compiler bug: instantiation widened a closed tag union Cannot print stack trace: stack tracing is disabled Aborted (core dumped)
This may be related to #11678 but --no-cache doesn't make any difference in this case.
