Bug ID: 375037
Summary: Style-checking hangs and uses all memory when opening
__builtin__.py
Product: kdev-python
Version: 5.0.80
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: Language support
Assignee: m...@svenbrauch.de
Reporter: m...@flherne.uk
Target Milestone: ---
Using head of 5.1 (301ca47).
When opening documentation_files/__builtin__.py under the kdev-python source
tree, KDevelop hangs. Memory usage rises over a few seconds and then KDevelop
gets OOM-killed.
Backtrace from just before getting SIGKILLed:
Thread 1 "kdevelop" received signal SIGINT, Interrupt.
