Hello again. Short update: I compiled Clang 7.0.0 latest Trunk against VS 2017 15.5.5 and it helped a little: * No more AST Crashes in Libclang.dll * Build time for the QDoc Module alone went down a little too: ** Clang 5.0.1 precompiled Binaries: 02 Hours 33 Minutes ** Clang 7.0.0 compiled from Trunk: 01 Hour 02 Minutes
Build time is still much longer than the normal 8-12 Minutes without
Clang. I will open a Bug Report about it in the next Days.
Have a sunny Sunday everyone.
