Sounds like the same, or similar issue as this one:
https://gitlab.freedesktop.org/mesa/mesa/issues/868

In that case it was caused by an LLVM bug that has been fixed in LLVM 10 for a
while but haven't made it into LLVM 9 yet.
If you use mesa 19.3 can you try if the same issue occours with ACO?

I can symphatize with your frustration, but I don't think this attitude is
helpful. Pierre-Eric and Alex are doing their best to solve this problem.
Insulting each other in the bugzilla is not constructive and won't bring us
closer to the solution.
