            Bug ID: 52311
           Summary: Starting executables from removable devices no longer
                    works with Wine 7.0-rc3-7-g3e73437ae8f
           Product: Wine
           Version: 7.0-rc3
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: wineserver

Hello folks,

just found by chance while checking some old bug reports.

Mount media/ISO image as usual and change to the directory where the executable
resides (= becomes working directory). Starting executable with 'wine
./setup.exe' results in:

--- snip ---
wine: failed to open "./setup.exe": c0000135
--- snip ---

--- snip ---
$ WINEDEBUG=+module,+server wine ./setup.exe >> ~/Downloads/log.txt 2>&1
...
0024:trace:module:get_load_order looking for L"C:\\setup.exe"
0024: get_key_value( hkey=0004, name=L"C:\\setup.exe" )
0024: get_key_value() = OBJECT_NAME_NOT_FOUND { type=-1, total=0, data={} }
0024: get_key_value( hkey=0004, name=L"*setup.exe" )
0024: get_key_value() = OBJECT_NAME_NOT_FOUND { type=-1, total=0, data={} }
0024: get_key_value( hkey=0004, name=L"setup.exe" )
0024: get_key_value() = OBJECT_NAME_NOT_FOUND { type=-1, total=0, data={} }
0024:trace:module:get_load_order got main exe default n,b for L"C:\\setup.exe"
wine: failed to open "./setup.exe": c0000135
0024: terminate_process( handle=ffffffff, exit_code=-1073741515 )
0024: terminate_process() = 0 { self=1 }

It worked with Wine 7.0-rc3 but with today's git it no longer does.

I suspect
https://source.winehq.org/git/wine.git/commitdiff/3e73437ae8f04a12200bf537758d22e5f9723637
("ntdll: Preserve the startup Unix directory unless it's on a removable
device.") being the culprit.

This works:

$ wine "e:\\setup.exe"
...

$ wine --version
wine-7.0-rc3-34-gb6dc8399087
