# This tests a bug where we would incorrectly parse the size of an array if that
|
|
# size happened to match an existing DIE offset. This happened because we
|
|
# misinterpreted that value as a reference to a DIE specifying the VLA size even
|
|
# though the form was a data form (as it should be).
