https://bugs.winehq.org/show_bug.cgi?id=42716

Bug ID: 42716
           Summary: IsDebuggerPresent returning TRUE
           Product: Wine
           Version: 2.4
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: kernel32
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

The function above is always returning true, depending on the machine. It seems
that the struct is not initialized correctly.

BOOL WINAPI IsDebuggerPresent(void)
{
     return NtCurrentTeb()->Peb->BeingDebugged;
}

Please check the Peb and BeingDebugged initialization.

As consequence, some applications sometimes cannot be run, such as MetaTrader5,
and we get a DialogBox:
“A debugger has been found running in your system. Please unload it from your
memory and restart your program”.
