I've tested with tip changesets:
ChangeSet@1.2025, 2005-09-30 01:38:04+04:00, sergefp@mysql.com
  Merge spetrunia@bk-internal.mysql.com:/home/bk/mysql-5.0
  into mysql.com:/home/psergey/mysql-5.0-bug13455

ChangeSet@1.2012.1.1, 2005-09-29 13:45:39-07:00, patg@krsna.patg.net
  New flags for new max-no-ndb build script to get a build that has 
  everything except NDB

How to repeat:
Get 5.0, compile with BUILD/compile-pentium-debug-max.
Run ./mysql-test-run t/view.test.

Doesn't crash for me when compiled with compile-pentium-debug, crashes only in -max builds.

I was able to repeat this crash even with ordinary debug builds, but only when using LinuxThreads threading library.

Fixed in version 5.0.14 (fix was pushed into build clone). Since the problem was introduced in the same version no ChangeLog note is needed.
