Debugger fault at startup.

After reading Pascal Chapier's message, I tried something else.  From a
fresh, unaltered build of R14B on a pretty bog-standard Ubuntu 10.04
installation typing "wx:new()." in the shell generates precisely the same
crash message.  This leads me to believe that wx is badly broken in R14B.
 Trying either "wx:new()." or "debugger:start()." in R14B on a completely
standard Windows XP system causes the VM to crash instantly, whether run as
werl.exe or erl.exe.  I happen to also have R13B02 on that machine and the
same problem is exhibited there.

It looks to me like wx support is really badly broken and has been for some
time.
