Short description of error
I open / begin a Blender file. I quit the program. Blender quits. I get a Problem Error Report: Blender quit unexpectedly.
Exact steps for others to reproduce the error
I'm not sure how to reproduce the error consistently. A new Blender file will let Blender quit without error,
This happens with more than 50% of my files, so I guess there's not much sense in appending one of them.
Sorry for not being more specific. Thanks for Blender!
Best,
Andreas Kjaergaard
Here's the full error report from MacOS:

It happened to my when I'm trying to reproduce this bug #75618, when I pulse the render image element in the render menu. I don't know if it is related.
Added subscriber: @brecht
Please attach a .blend file anyway.
And test with the latest build, there may have been a temporary issue on 2020-03-31.

I had the same issue, crashes on quit around 50% of the time, with a macOS build of about the same date. For me it doesn't happen anymore with the 2020-04-11 build, so good to try with the latest build as stated above.

Thanks for your swift replies.
Indeed, the newest available build – Blender 2.83 Alpha April 11, 16:43:32 -
85de07e64cmacOS 64 bit 194.49MB – seems to fix the problem. I should have checked. Sorry.Now, surely, it must be irrelevant, but if not, here's a file that gave me consistent errors when quitting: https://www.dropbox.com/s/4ey5k84mn6kygb2/Sfinx%20Fluids%2006%20%28ny-ny%20tekst%29.blend?dl=0
The problem re-appeared with 2.90 alpha for me, a crash upon quitting in about 50% of the time. Looking at the crash report, I suspect it is still the same problem?

I'm seeing the same backtrace on Linux now. This happens after selecting an object in the 3D viewport.
Somehow the grease pencil shader pointers are getting corrupted, even though no grease pencil objects are being drawn.
#75958 may be related.

@fclem, there are two issues here. One is that this code is not valid in general, but it's used in multiple places in the draw manager.
The compiler may add padding between members or choose to use different memory alignment for arrays or structs. I'm using clang on Linux which is also used on macOS, and probably it has some differences with GCC.
The simple solution is this. I haven't seen issues with other usages of this casting, but to be on the safe side they would all need to be changed.
The other problem is that grease pencil is being used at all when there are no grease pencil objects. In most cases it's disabled, but it seems not in the select drawing. That can be fixed using:
