llvm-config --version == 8.* fails

[graeme-lockley]

Noting that only works for 5.* - any thoughts of migrating up to 8.*?

Currently, when attempting to run with 8.*, results in the following:

Pass 'Interprocedural Sparse Conditional Constant Propagation' is not initialized.
Verify if there is a pass dependency cycle.
Required Passes:
Assertion failed: (PI && "Expected required passes to be initialized"), function schedulePass, file /tmp/llvm-8-20190526-56764-ebirf6/llvm-8.0.0.src/lib/IR/LegacyPassManager.cpp, line 753.
Abort trap: 6

How can I help?
