           Summary: `winetricks -q ffdshow` throws an access violation in
                    usp10.dl (winetricks-test)
           Product: Wine
           Version: 5.7

      Distribution: Gentoo

Note: I've only been able to reproduce this when running winetricks-test; I
suspect it's related to `winetricks sandbox`, though running that beforehand
outside of winetricks-test doesn't reproduce the bug. Marking "UNCONFIRMED"
accordingly.

This is a regression, introduced by:
da604dce3493cbd79a201cf0d1885c848c10eac4 is the first bad commit

Running the installer with /silent runs it in quiet mode. It appears to install
fine, but during installation, a message box appears showing:
Access violation at address 00E2A834 in module 'usp10.dll'. Read of address
00000068.
