Comment (by rootfather):

 I managed to compile the latest SDL2 codebase and I attached both the 64-
 and 32 Bit binaries.

 First, this is not a bug in ScummVM, but in SDL2 that got recently fixed.
 [https://bugzilla.libsdl.org/show_bug.cgi?id=3147].

 There are two reports in the SDL forums that show similar issues, see
 https://forums.libsdl.org/viewtopic.php?p=51329#51329 and
 https://forums.libsdl.org/viewtopic.php?t=11913.

 The bug got fixed with SDL2 revision 17e0ded12e6f.
 [https://hg.libsdl.org/SDL/rev/17e0ded12e6f]

 Using the HG DLLs I attached fixed the problem for me. However, there is a
 very small issue: After unlocking in windowed mode, the ScummVM window is
 black until you move the mouse cursor. I *assume* that this "black state"
 was what caused the crash in 2.0.4, because it seems that the fix in
 17e0ded12e6f is more of a workaround.

 I read something about "unsupported pixel formats" being the cause for the
 crash, but due to my limited knowledge, I cannot confirm if this applies
 for ScummVM or if there is something we can fix.

 '''Conclusion: Not a ScummVM bug. Bug in SDL2 2.0.4. Fixed in later
 revisions.'''
