System Information
Operating system: Windows-10-10.0.17134 64 Bits
Graphics card: AMD Radeon (TM) R9 390 Series ATI Technologies Inc. 4.5.13521 Core Profile Context 24.20.11016.4

Blender Version
Broken: version: 2.80 (sub 51), branch: blender2.7, commit date: 2019-03-28 00:40, hash: rBcd92f8ea4626
Worked: (optional)

Short description of error
I had to shut down Blender as I needed to reboot my PC. When I restarted, none of the project files I'd made would load, Blender would hang for a couple of seconds and then just shut down.

I upgraded to the latest build (March 28th 2019) and tried again, no effect. I also unchecked the "Load UI" button, as I'd used a split view window for the first time before the crash.

I then loaded Blender, saved the default box as a new file and tried to load that - it crashed too. That file is attached.

Exact steps for others to reproduce the error
Simply try to open the file.

I have tested and I can open the file first time, but if try to reopen it again I get a crash:

I have used the last version of source code and compiled in Windows 10 64 bits

EDIT: Testing again, every time I get different error and depends if you open from splash screen or File>open menu.

I can not reproduce this on my end (linux).

@Ray Molenkamp (LazyDodo) can you reproduce this too (we can double confirm that this is probably a windows issue).

@Sebastian Parborg (zeddb) given @Antonio Vazquez (antoniov) stack trace seems to suggest mem issues,try running with ASAN see if that has anything to say about it.

can repro, different callstack though

BTW, I can't even start blender with ASAN. I get the following errors:
