This is an adaptation of libstable by Javier Royuela del Val (see README for details) that creates a Python interface for use in SciPy.
A segmentation fault happens in: stable_integration_QAG2, ie, inside call of gsl_integration_qag
When this problem is fixed, the assignment: dist.stable_pdf_point=stable_pdf_point_LEVY; in stable_pdf.c should be removed.
