Sprite packer causes Out of memory error



Unity editor crashes on sprite packing with out of memory exception, if there is not enough RAM. Tested with 4GB RAM

Reproduction steps:
1. Open the project
2. Try to pack sprites using the DefaultPackerPolicy

Expected: sprites get packed
Actual: crash, with possible long freeze before it

Not reproduced on: 5.6.0b2
Reproduced on: 5.6.0b3, 5.6.0p1, 2017.1.0b1
Regression introduced on: 5.6.0b3

On 2017 versions, it doesn't crash, but freezes for 15min+
On 5.6.0b2 and before, it takes just a few seconds to pack sprites

Fixed on 5.6.1p2, 2017.2.0a1

    4GB RAM is not enough for this project because you have to compile many files and it takes time too. The share a complete criteria which you can follow and then do work.

    This appears to be fixed in v5.6.1p1, but was not noted in the release notes.
