GNOME Bugzilla – Bug 328609
segfault in TreeSelection.forEachSelected()
Last modified: 2006-03-19 12:57:46 UTC
Steps to reproduce: When I run forEachSelected() on a TreeSelection inside a TreeSelectionListener I get a reproducable segfault as soon as I select (by Ctrl-Clicking) a second row.

Created attachment 61535 [details] [review] Patch to prevent the segfault. This patch should also fix bug 172645. The cause of this bug is that our fedata struct was freed and then when the two column comes around to try to use it, it is completely null, so all our attempts to extract Handles fails (and crashes as a result since the JNIEnv is null and nothing can be done). Since the flow of execution goes like: jni startForEach calls - gtk+ gtk_tree_selection_selected_foreach which then calls - static jni forEachFunc (iterating over each treesel) then execution returns back to startForEach So the proposed solution of freeing everything _after_ the gtk+ function completes should be correct.
The patch looks good. 2 comments (both very minor): 1) I am of the opinion that incorrect code should not be commented out, but removed instead. 2) "*env)->DeleteGlobalRef(fedata->env, fedata->obj);" -> Instead of "fedata->env", we can use "env", since they're the same.
Modified patch per comment #2 and applied to CVS head, closing.
