Bug ID: 56256
           Summary: Windows Sysinternals Process Explorer 17.05 shows
                    incomplete user interface (32-bit).
           Product: Wine
           Version: 9.1
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

With WINEARCH=win32 procexp.exe shows just the menubar,
other parts of the userinterface seem missing.

This seems related to this line:
0124:err:seh:dispatch_user_callback ignoring exception c0000005

Successful startup, when correcting stackpointer in windbg.

The crash happens because of having an invalid memory address in register $esi.

I think this register $esi is getting pushed to the stack at 0x4aa605,
and getting retrieved at 0x4aa9df.

When this part is executed the third and the following times,
the stackpointer is 4 bytes too low,
when $esi should be retrieved from the stack.

Unfortunately I could not find out where this is caused.
There are several functions called, but I saw no obvious candidate for
a wrong calling convention.

If I adjust the stackpointer in debugger before the pop instruction,
procexp could startup successfully (session attached).

0x4aa605:    push   %esi
0x4aa9df:    pop    %esi
