@fmoessbauer Might be related to recent changes of underfilled block arithmetic in pattern code?

This seems to be not a problem of the local view, but anywere below in DART. I tried to track down the bug, but without valgrind I was not able to find it. I guess that we try to access memory which has not been allocated by dart, but I cannot prove that.

@rkowalewski please have a look the bug. I did enhance the unit test in branch bug-227-localview

Marked as duplicate: This is another effect of the defect reported in #280

Only occurs for odd number of units and unaligned local memory.
