Description:
we did something wrong in the 5.0 code (not in older versions) in 2003, so this crash exists in 5.0.0

How to repeat:
just myisamchk -r some file (repair with sort).

Suggested fix:
will fix it today.

Fixing it is too complicated for me as the type of THD::killed changed in 5.0.
Holyfoot, this bug is now assigned to you. Its origin is in your changesets

  two KILL commands implementation (version 2)
and
ChangeSet 1.1494.44.10 2003/04/08 19:18:33 hf@deer.mysql.r18.ru
  SCRUM
  two KILL versions
  code trimming with headquarter's suggestions 
both in the 5.0 tree.
A testcase for the bug is:
just try myisamchk -r on any MYI file, it segfaults. Problem is in killed_ptr().
