WIN Latest nightly build (2019/08/27 05:33): Compile not possible

[harryboo]

With the latest nightly build it is not possible to compile an example if this is set in the preferences:

compiler.cache_core=false

Error msg:
german-Das System kann den angegebenen Pfad nicht finden.
english-The system cannot find the specified path.

If i set this option to TRUE the compilation is possible.
