Always happy to help if you're interested in looking into using 
dcompute. I can't remember if we've talked about it before, but 
if you were wanting to use it you'd need OpenCL 2.x (explicitly 
the 2.x version series, or make sure the 3.x implementation 
supports SPIRV) running on that 20 logical core box (or if it has 
GPUs attached to it, CUDA (any version should do) for NVidia GPUs 
or OpenCL 2.x (as above) on any other GPUs).

With regards to the stack corruption there is 
https://github.com/ldc-developers/ldc/blob/master/gen/abi/x86.cpp#L260 which has been there for some time. It would be fairly simple to issue a diagnostic there (although getting source location from there might be a bit tricky) for when there is both a `byval` and an alignment specified.

Or you could use grep with `--output-ll` as noted by Johan 
https://github.com/ldc-developers/ldc/issues/4265#issuecomment-1376424944 although this will be with that `workaroundIssue1356` applied.
