Hi, Tom.

I can reproduce. The crash is in Progress Bar control code, PBM_STEPIT handler.
It happens that MinVal == MaxVal == 0 at that point, and that indeed leads to
division by 0. Your backtrace is showing wrong location for some reason, I get
this:

Backtrace:
=>0 0x00007f6e90d9bfdb ProgressWindowProc+0x52b(hwnd=0x700cc, message=0x405,
wParam=0, lParam=0)
[/ssd/data/wine/build/wine64/dlls/comctl32/../../../../wine-git/dlls/comctl32/progress.c:662]
in comctl32 (0x000000000020c5f0)

I simple workaround makes it start and open a toolbar-like window with a row of
buttons. I will write some tests for this and get proper fix.

Thank you for detailed report.
