--- Comment #1 from Bernhard Übelacker bernhardu@mailbox.org --- Created attachment 71208 --> https://bugs.winehq.org/attachment.cgi?id=71208 Workaround by ignoring pointers outside of the current stack.
Forgot to mention that the patches for bug #52105 are also needed to get to that issue.
Attached patch ignores pointers that are outside of the current stack.
That made gdb.exe working that far that I can debug gdb.exe with it :-)
