Terminate called after throwing an instance of 'Manta::Error'

Hi,

while rendering a scene, Blender throws following error, and terminates:

terminate called after throwing an instance of 'Manta::Error'
  what():  can't clean grid cache, some grids are still in use
Error raised in extern/mantaflow/preprocessed/fluidsolver.cpp:33
Abgebrochen (Speicherabzug geschrieben)

Translated: Killed (core dump written). Unfortunately, this is a lie.

I’ve prepared the system to produce a real core dump now, and will follow up with a backtrace, if I’m able to reproduce the crash.

Please use developer.blender.org for bug reports.
