Python-Ubuntu 12.04中的细分错误

Question

My program is coded in Python, and it calls a bash script in a vte window:

In 14.04 or 14.10 ubuntu system, no problem. (python 2.7.8)

But, in ubuntu 12.04, the window closes with this message: (python 2.7.3)

segmentation error

To debug, I've tried to use gdb with this line:

gdb -ex r --args python my_program.py

The output of gdb at the end is:

Program received signal SIGPIPE, Broken pipe.
0xb7fdd416 in __kernel_vsyscall ()

I know it's a problem with the bash script, but I don't know realy what is the problem. The line to call the bash script is:

self.child_pid = self.v.fork_command(None, ['/bin/bash', cli, '-f', '-d', dest, '-u', adresse, v])

It is possible to debug this for ubuntu 12.04 ? How can I do ?

Answer 1

I have found a solution with insering a sleep 1 in the bash script (cli), just after the ffmpeg command:

ffmpeg -y -i "${M3U2}" -vcodec copy -acodec copy "${Directory}/${PROG}_${ID}.mkv"
sleep 1
