Zach,

Will my CL avoid the crashes?

For Float32List.view_A01_t02 and Float64List.view_A01_t02, on hardware I get:

Unhandled exception:
RangeError: Offset (1) must be a multiple of BYTES_PER_ELEMENT (8)
#­0 Float64List.Float64List.view (dart:typed_data-patch/typed_data.dart:195:16)
#­1 checkIntersection (file:///home/user/dart1/dart/tests/co19/src/LibTest/typed_data/Float64List/Float64List.view_A01_t02.dart:30:15)
#­2 main (file:///home/user/dart1/dart/tests/co19/src/LibTest/typed_data/Float64List/Float64List.view_A01_t02.dart:44:20)

For toUint32x4_A01_t02 I have the same failure, so that must be an unrelated problem.
