Description
G1 crashes during young and full GCs on Linux.

                                    

Comments
EVALUATION

The apparent reason of the crash is concurrent resizing of a GrowableArray that is used as a storage for HeapRegionSeq, and reading from it.  During the resize procedure multiple kinds of races are possible which all cause HeapRegionSeq corruption from reader's point of view.
