Python - Program received signal SIGSEGV, Segmentation fault

Question

I'm traying to lunch a python code for my degree thesis. I know it can work...but not on my pc!

I'm using Ubuntu 14.04 and first I receive this error:

segmentation fault (core dumped)

I tried to launch

gbd python (gbd) run MainLogic.py

Here the result:

Starting program: /usr/bin/python MainLogic.py

After I launched the command ""bt" for the backtraking:

Perhaps there is something wrong in my packages and my Ubuntu setup, because in other pc the code works fine. How can I fix this segmentation fault?

Answer 1

Try updating to the latest gcc version. It should be fixed starting from somewhere in 4.8.2 or 4.8.3.
You could also try updating to gcc 5.*.

If neither of those don't work, you could try the hackish way of patching /libstdc++-v3/python/hook.in, as described here .
