*** This bug has been marked as a duplicate of bug 349990 *** Sven, are you hinting that current 1.7-py3 branch is work-in-progress with regards to python-3.4.3? If you want to put it that way, yes :) Or rather, all Python 3 versions are broken with Python 3.4.3 and I didn't yet manage to fix it. |
I've built head of 1.7-py3 against Python 3.4.3 using kdev-platform 1.7.1 While parsing the file with the following contents, kdevelop segfaults: def iterate_tree(tree, depth, callback): iterators = [iter(tree.items())] args = [] while iterators: True while depth: for k, v in iterators[-1]: args.append(k) Here is the kdevelop log: =============================== kdevelop(5981)/kdevplatform (shell) KDevelop::PluginController::loadPluginInternal: Attempting to load ' "kdevpythonsupport" ' kdevelop(5981)/kdevplatform (shell) KDevelop::PluginController::loadPluginInternal: Checking...
