! - compiler: cce19

! - expected: check=pass (trusted; elision + model)
! - actual: crash  (crash: SIGABRT; without mandatory: crash: SIGABRT)
! - verdict: compiler_bug by rule R20-runtime-bug: a legal program fails at run time, deterministically, against an expected value
!   from two or more independent sources with an executed witness, and another toolchain, mode, arch or the elision gives the
!   expected value
! - reason: expected trusted check=pass (elision + model): stored main verdict: elision + model agree; witnesses:

! - legality: legal: offload.engine.prerun.check accepts it (rerun: offload.engine.rules with the
