Ok, I think we are getting closer. I recompiled salomegeometry with CPPFLAGS=-D_OCC64. I recompiled pythonOcc too even though I didn't know if it was necessary (I guess it is to avoid linking issues). Know all three unit tests are successful ;-) which is nice. But running the PAF tutorial I still end with a segfault :( I attached in PAF1.py and PAF2.py two sequences of python calls that make it crash. And also the corresponding backtraces. I haven't still compiled OCC in debug as I wanted to first give a try to the -D_OCC64 flag. I'll do it if you feel like some info is missing.
Look, I would perfectly understand you get peaced off with this and want to give it a break. Thanks anyway.
