verify hanging with #include <FastLED.h>, Arduino 1.6.4

With ‘#include <FastLED.h>’ verify starts but never terminates.

Output in verbose mode:
Verwende die Bibliothek FastLED-3.0.3 im Ordner: C:\Users\Det\Documents\Arduino\libraries\FastLED-3.0.3 (legacy)

Happens every time even with empty code segment independend of compiler settings.

If I delete the include-statement or include other libraries verify works properly.

I use Arduino 1.6.4.

I’m getting mad due having no idea where to search. Any hints?
