Tom Jack has found a bug in the implementation of transp for Glue (and
hcomp for U) in Cubical Agda, where a system that should be
[psi -> ..., forall i phi -> ...]
became
[phi -> ..., forall i phi -> ...].
Details of the bug (and the fix) are at:
https://github.com/agda/agda/pull/6197
Question: can one exploit this bug with reasonable resources?
In particular, we are using for a rather short test case that either
- makes Agda crash, or
- proves False.
Ideally, this test should run in reasonable time (less than a minute,
say) using reasonable resources (not more than 4G memory), so we can add
it to the regression test suite.
