~Environment Cross compiled Python 2.7.15 for ARM Cortex-A7 target, Linux Kernel 4.18 uname -a: Linux Test-0002 4.18.13 #1 SMP Wed Oct 31 11:20:07 CET 2018 armv7l GNU/Linux ~Description of the problem Importing the "ctypes" module in order to load shared libraries causes a segmentation fault: root [ /tmpfs/root ] $ python Python 2.7.15 (default, Nov 29 2018, 13:57:56) [GCC 8.2.0] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import ctypes Segmentation fault I have found a similiar issue here: https://bugs.python.org/issue11048 But the changes are already applied in 2.7.15. Here is the GDB output similiar to the link I posted: (gdb) file python2.7 Reading symbols from python2.7...done. (gdb) run -c "import ctypes" Starting program: /usr/bin/python2.7 -c "import ctypes" warning: Unable to find libthread_db matching inferior's thread library, thread debugging will not be available.

I also attached the strace log of the command 'python -c "import ctypes"' Thank you in advance! ---------- components: ctypes files: strace_python.log messages: 330696 nosy: n0s69z priority: normal severity: normal status: open title: importing "ctypes" immediately causes a segmentation fault type: crash versions: Python 2.7 Added file: https://bugs.python.org/file47954/strace_python.log _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue35350> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
