Its function cell is > a vectorlike which pr reports as #. The most likely explanation is that it used to be a byte-code-function-p object but was somehow GC'd too early. If that symbol is interned, why would its function definition get GC'd at all? Similar crashes have occurred several times. This is the first time I analyzed it to see what data it is operating on. I will do it again next time. -- Dr Richard Stallman President, Free Software Foundation 51 Franklin St Boston MA 02110 USA www.fsf.org www.gnu.org Skype: No way!
