--- Comment #3 from Bernhard Übelacker bernhardu@mailbox.org --- Just a short addition: It looks like MaLauncher.exe creates some threads, where at least one checks from time to time by IsDebuggerPresent if there is a debugger attached. This thread seems after the call to the unimplemented function in the other thread and the start of 'winedbg --auto' suspended. But ContinueDebugEvent releases this thread, IsDebuggerPresent returns true, and ExitProcess is called. Unfortunately while winedbg is still in the middle of its work.
