Bug ID: 437380
Summary: Background Parser causes crash when scanning python3
libraries
Product: kdevelop
Version: 5.3.1
Platform: Debian stable
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kdevelop-bugs-n...@kde.org
Reporter: devnull...@protonmail.com
Target Milestone: ---
Application: kdevelop (5.3.1)
Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.0-16-amd64 x86_64
Distribution: Debian GNU/Linux 10 (buster)
-- Information about the crash:
- What I was doing when the application crashed:
Background Parser is scanning python libraries
The crash only occurs when certain libraries are imported:
I created an empty python file and added import lines as follows, and it
crashed on the final import (pandas)
#!/usr/bin/python3
import bs4
import multiprocessing
import os
import pathlib
import json
import time
import logging
import pandas as pd
matplotlib also causes the crash
all above libraries are the debian package versions
mplfinance installed from pip also crashed
The crash can be reproduced every time.
-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
