Description
This issue was identified several months ago and is currently being investigated by the compiler vendor (OLCFHELP-19210). This E3SM GitHub issue will serve as a placeholder for tracking its progress.
The table below summarizes the test results. These results are from running the e3sm_developer test suite without debug cases, as building debug cases with the Cray Clang compiler took an excessive amount of time.
| Test Result | crayclang (cce/15.0.1-current) | crayclang (cce/17.0.0) |
|-------------------|---------------------|--------------------|
| Avg. Build Time (secs) | 1137 | 1619 |
