Hi Pablo,

This one is yours:

TEST /home/buildslave/buildslave/clang-cmake-aarch64-quick/stage1.install/bin/clang++

1.      <eof> parser at end of file
2.      Per-module optimization passes
3.      Running pass 'CallGraph Pass Manager' on module
'/home/buildslave/buildslave/clang-cmake-aarch64-quick/test/test-suite/MultiSource/Benchmarks/7zip/CPP/7zip/Archive/Cab/CabHandler.cpp'.
4.      Running pass 'Jump Threading' on function
'@_ZN8NArchive4NCab8CHandler4OpenEP9IInStreamPKyP20IArchiveOpenCallback'

Attached the reproducer. Better revert while we investigate, as this
will take a while.

cheers,
