Bug ID: 50973
           Summary: winedbg --gdb exits immediately
           Product: Wine
           Version: 6.5
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winedbg
          Assignee: [e-mail]

Hi,

similar to https://bugs.winehq.org/show_bug.cgi?id=50117 but from version 6.5
onwards, "winedbg --gdb" exits immediately and runs the program, instead of
showing the gdb shell, which used to stop after loading but before running the
program.

Version 6.4 does not have this issue.

I've git-bisected it down to this commit:

28fe84da45bea7de56539b50eac8ebcec54342de
    Author: Alexandre Julliard

    ntdll: Load the main image from the Unix side.

Unfortunately this is a massive commit, and I can't right now put in the time
to dig deeper into what might be causing the gdb mode to exit early. Also it
doesn't revert easy on the latest version, 6.6. Maybe someone has a quicker
understanding of where to look within that change. If not I can start digging
deeper myself.

To reproduce:

winedbg --gdb notepad.exe

OS info:
latest Archlinux x86-64
