[cfe-dev] Clang Build error

[Jonas Toth via cfe-dev]

Hi,

you can of course debug it, but the build does not contain Debug
information. The code will be optimized and not correspond 1to1 to
source code.

You can of course use std::cout and friends to see whats going on.
Please note, that `RelWithDebInfo` exists, too. But that build type will
probably suffer from high RAM usage.
