Bug ID: 47871
           Summary: gameux:gameexplorer crashes randomly
           Product: Wine
           Version: 4.17
          Hardware: x86
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gameux
          Assignee: [e-mail]
          Reporter: [e-mail]

gameux:gameexplorer crashes randomly on Windows 8 and 10:

gameexplorer.c:633: prepared EXE path:
L"C:\Users\winetest\AppData\Local\Temp\wct"
gameux:gameexplorer:0940 done (-1073741819) in 1s
Test failed: crash (c0000005)

Every line with a 'mixed' result is a date when the test crashed:
https://test.winehq.org/data/tests/gameux:gameexplorer.html

Unfortunately there is no backtrace but the last visible trace is in
test_install_uninstall_game() which is the last function to be called. So that
narrows down the range where the test crashes.

The crash happens in both 32 and 64 bit tests on the following configurations:
* cw-rx460-32 *real hardware* machine running Windows 8.1
* w8 and w8adm both Windows 8.1 TestBot VMs, the former running with elevated
privileges and the latter just in an administrator account.
* w1064v1507 a Windows 10 1507 TestBot VM (elevetated privileges).

--- Comment #1 from François Gouget  ---
Some of the crashes look like this:

gameexplorer.c:98: prepared EXE path: L"C:\Users\winetest\Documents\tests"
gameux:gameexplorer:0428 done (-1073740791) in 0s
Test failed: crash (c0000409)

Where 0xc0000409 == STATUS_STACK_BUFFER_OVERRUN.
So both types of crashes probably have the same source: memory corruption.
