XEmacs 21.4-14 hangs when editres client asks 'Select widget in client'.
XEmacs 21.5 does not hang.
To reproduce.
Start xemacs
$ xemacs-21.4.14 -vanilla
Start editres
$ editres
In editres from menu 'Commands' issue the command 'Get Tree' and click on
XEmacs frame. The editres pane will display the tree of XEmacs widgets.
Then in editres from 'Tree' menu issue the command 'Select Widget in Client'.
Click on XEmacs toolbar. Editres says that request is sent to the client,
XEmacs hangs, some time after Editres says that "it appears that this client
does not understand the Editres Protocol".
XEmacs prints in the console:
xemacs: X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 3 (X_GetWindowAttributes)
Resource id in failed request: 0x0
Serial number of failed request: 1797
Current serial number in output stream: 1798
Attaching to the process with GDB gives the following backtrace:
