Certain keys crash XEmacs with MacOS X 10.0.1

This bug report will be sent to the XEmacs Development Team, not to your local site managers!! Please write in English, because the XEmacs maintainers do not have translators to read other languages for them. In XEmacs 21.2 (beta46) "Urania" [Lucid] (powerpc-apple-darwin1.3) of Tue Apr 3 2001 on gryffindor configured using `configure --pdump' Please describe exactly what actions triggered the bug and the precise symptoms of the bug: Pressing the apostrophe key leads to a crash. That seems to independent from the buffer mode, it happens in gnus and in all other buffers. I can reproduce this behaviour at any time I want (which is not very often ;-).

Abort (core dumped) I loaded the core file with gdb (like XEmacs said) but "where" simply says "No stack.".
