[llvm-dev] Build Error from mlir-capi-ir-test

[Mehdi AMINI via llvm-dev]

Hi,

It seems like you were unlucky and checked out a buggy revision: this was a
known bug a couple of days ago. Please git pull and try again, let us know
if you have any issues!

Also MLIR folks communicate mainly here:
https://llvm.discourse.group/c/mlir/31

Best,
