Source: llvm-toolchain-12 Version: 1:12.0.1-9 Severity: serious Tags: ftbfs Justification: fails to build from source (but built successfully in the past)

I can't tell whether 1:12.0.1-10 still has this bug, because it failed in a different way on armel and armhf (I've opened a separate bug for that). smcv
