Hi, The way to the latest xemacs crash: % xemacs -vanilla, M-x gdbsrc RET filename RET In gdb shell: $ core core Here is a report of the last few seconds: XEmacs tries to load the source file to go to the code line where the core was generated. The window gets splitted, one can see the source code in the lower window, its mode line says "entering gdbsrc mode". But the two windows doesn't get a separating mode line. Now XEmacs freezes and vanishes into a core.
