Hi Terrence,
I'm one of the Stackless developers. You didn't mention the Stackless
version, architecture and - less important - compile time options.
Without this information nobody can help you.
Then, please make sure to use the latest version of Stackless. You can
get the source from www.stackless.org. We fixed quite a few segfaults
over the time.
If the bug persists with the latest version, you can open an issue on
bitbucket:
1. Get a bitbucket account and sign in.
2. Open a new issue on
https://bitbucket.org/stackless-dev/stackless/issues?status=new&status=open
King regards,
Anselm

hello, I'm not sure of the proper way to report all relevant details such
as architecture, etc, but here is an initial cut at an issue report. I am
using the nagare web framework which uses Stackless Python. It dumps core
and here is the backtrace:
