With dmd trunk trying to compile vibed after fixing several array 
declarations from C style to D style I'm getting this error that 
I do not understand:
-----------
Building vibe-d 0.7.21-rc.2 configuration "libevent", build type 
debug.
Running dmd...
/home/mingo/dev/d/src/install/bin/../../../src/phobos/std/container/array.d(432):

  , __ctmp3047).this(this, 0LU, this.length())) of type

Any clue from the experts ?
