Hi all,
I am running a script that cranks out multiple plots in a loop. The script
has plt.show() as the very last line as I think you are supposed to do.
All plots show up, but I get a seg fault (sometimes a bus error - I haven't
figured why it occasionally does that) when I close the last plot and the
script exits. I was wondering if someone could help me figure out what
info to grab to determine what is causing it. I use gentoo and recently
did an upgrade world, so I am guessing some new library is not playing
nicely as this always seemed to work before. Also, when I switch to Qt4Agg
backend,
everything works as expected, but if I can help iron out a bug, I would
like to - I really think that matplotlib is an excellent piece of software.
Pertinent info:
uname -a:
Linux dayd 3.10.15-gentoo #6 SMP Sat Dec 14 15:53:47 MST 2013 x86_64
Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz GenuineIntel GNU/Linux
Matplotlib version - 1.3.1
matplotlibrc:
backend: TkAgg (Qt4Agg works as expected)
interactive: False
because it segfaults
python3.3 testplot.py --verbose-helpful > output.txt
outputs nothing
gcc --version:
gcc (Gentoo 4.8.2 p1.0, pie-0.5.8) 4.8.2

script to reproduce the problem:
import sys
import matplotlib.pyplot as plt
def main():
for x in range(6):
plt.figure()
plt.title(x)
plt.plot([1,1],[1,1],'r.')
plt.show()
if __name__ == "__main__":
sys.exit(main())
I found some instructions on how to get debug info when you install a
package in gentoo. If anyone else can recreate this or need some more info
from me - please let me know. I will do what I can.
Thanks!
