Hi Chris,
Thanks for the reply.
However, the error occurs even if I don't do anything, that is, even if I
simply import the library and exit() after that.
I created a file a.py whose contents were the following:
import pyossim
exit()
Upon execution, the log was as follows:

It looks like you are using matplotlib, and matplotlib is the one

The reason is that the process tries to write to a memory address it

This is confusing. A seg fault kills the process immediately. No
exception (in the Python sense of that word) is raised.

Unfortunately (i guess), I am not doing any XML. However, I am taking
the previous suggestion of putting print lines in every other line of
my code and then seeing where it crashes. Hopefully, that will solve
the problem.

if you don't know exactly which line of code causes the segfault, use
print statements to determine that. then try to either
redesign/refactor so that line isn't necessary, or protect its
operation somehow.
if you do know, tell us what it is and we might not need to see all
your code.

yes, insane. Thanks again.
