could you tell me a little more about your configuration (CPU, OS version, clang version) and attach an uncompressed image to test?
thanks

CPU: Variety, similar to Amazon's EC2s
OS: CentOS Stream, version 8
Clang: clang version 9.0.20190721
I'll be trying to get a small, reproducible test case as sample program and see if I can figure out exactly what it going wrong.
We have multiple teams using this code, each having their own copy of the source. As far as I'm aware we are the only team that has run into this issue.
We first encountered this issue with just having clang optimization turned on, so we added a workaround by disabling optimization using a pragma. The complier flag to use the new pass manager is causing the bug to resurface. Our current stopgap solution is to disable the new pass manager and keep the pragma in the .cpp to turn off optimizations.
