| Description: |
(text/x-fossil-wiki)
The following script causes Tcl to abort:
<code><verbatim>
oo::class create object
trace add command object delete {apply {{name1 name2 action} {
namespace delete [info object namespace $name1]
}}}
rename object {}
</verbatim></code>

When a trace on the deletion of the command of the object explicitly deletes the namespace of the object, <code>tclOO.c/ObjectNamespaceDeleted()</code> must take care not to clean up the object itself so that <code>tclOO.c/ObjectRenamedTrace()</code> has a valid object pointer to work with. Fixed in commit bee7f97ad6521604. | |||
