(Issue introduced by3b9813fe50
)Short description of error
During the test of cycles_lights - Portal blender crashes.
Exact steps for others to reproduce the error
You need the debug heap (asan on linux should also catch it) to trigger this one.
During the load of lib\tests\render\light\portal.blend the versioning code reads beyond the end of a buffer.

Hi,
I am having the same problem, I have been making a large test file in 2.8. The last change I made was to make a master collection containing a window frame and portal. I instanced this collection to the scene a dozen times. Everything was loading fine on the Mac OS build for 13th may but the build for the 14th may build crashes when opening the file. I have an archive scene without portals and that opens just fine in the 14th may build. I cannot seem to reproduce the error on a smaller test file. The file that crashes as around 10M faces and takes 6GB ram.
My system is Operating system: Mac Pro (Mid 2010) macOs 10.13.3
Graphics card: Radeon RX 580
I haven't generated a bug report because I cannot reproduce the error as yet, I have no idea if the size of the file is related. The file works fine on all older Beta versions. Just the 14 May is causing problems.
Hope this helps.
Eric

@DiveMeCarzy, I think you replied to the wrong bug.
There was a crash for macOS in recent builds with display of images in the 3D viewport, that should be fixed in the latest build.

Please check if this is fixed now, I didn't get ASAN to work right now..
can confirm it's fixed.
