well, the way it is currently designed to would be to ‘crash’ resp. exit with
an error right on starting up the
non-framework interpreter. But besides that it’s curious that its python
actually crashes with the macosx
backend, which I have never seen with Fink’s non-framework Python. Just tested
this with 1.4.0rc3 and
Python2.7 (previously with 1.5.x HEAD in Python3.4), and it works the same -
the same little quirks,
but no signs of performance or stability problems.

So it affects other backends besides macosx or even all? Yes, this seems to be
rather Anaconda-specific.
I’ve looked for anything special in the build options, but besides adding the
right include and linker paths
there isn’t really anything.
Cheers,
Derek
