Committed to trunk a forward porting of the logic in the 8.5 branch on how to react when NULL is returned. Please comment if the solution is not satisfactory. Looks like the bug came in with TIP 357 implementation. rkeene added on 2013-05-19 01:45:36: File Added - 463423: tcl-8.6.0-bug3613569-1segfaultonnotmp.diff | |||
