I have tried it out, and can confirm that using debugging tools (namely<br>
valgrind), will allow you track down the issue (valgrind reports it<br>
from within python, running a python without debug symbols may<br>
obfuscate the actual problem; if that is the limiting you, I can post<br>
my valgrind output).<br>
Since you are running a linux system, I am confident that you can run<br>
it in valgrind to find it yourself. (There may be other ways.)<br>
<br>
Just remember to run valgrind with `PYTHONMALLOC=malloc valgrind` and<br>
ignore some errors e.g. when importing NumPy.<br>
<br>
