            Bug ID: 56211
           Summary: Wine doesn't set dll path properly when more than one
                    dll with the same name is present
           Product: Wine
           Version: 9.0-rc5
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: wine-bugs(a)winehq.org
          Reporter: dark.shadow4(a)web.de
      Distribution: ---

Found while investigating bug 56209. I'm using MR 4518 (important later).

Using msvbvm50.exe from winetricks (vb5run), the exe unpacks its own
ADVPACK.DLL in its current working directory. However, due to the loading
order, wine still loads its builtin advpack.dll

However, the loader still sets the nt_path to the originally requested DLL, not
the one that actually gets loaded. So the wineserver has mapping->fd
unix_path =
/home/fabian/Programming/Wine/wine/dlls/advpack/i386-windows/advpack.dll
nt_path = /home/fabian/.wine/drive_c/users/fabian/Temp/IXP010.TMP/ADVPACK.DLL

When entering virtual_map_builtin_module we get the filename from the mapping
with line
> filename = (WCHAR *)(image_info + 1);

This is how you can easiest test that discrepancy. When using the GDB
integration MR, that filename is passed to GDB, so it never loads the right
symbols for advpack.dll.

--- Comment #1 from Fabian Maurer <dark.shadow4(a)web.de> ---
According to Alexandre, this is intended behavior, the program shouldn't be
aware that a builtin dll was used.
