Segmentation fault (core dumped) when running test suite after building from sources

[njourdane]

I get a segfault when running the test suite (python3 ./run_tests.py) after successfully building python-occ from sources.

I disabled some tests in order to isolate the problem.

After disabled test_write_step_file and core_extend_dataexchange_unittest, the tests passes.

ok, that's something I noticed on osx as well. I have no clue so far where it comes from

I ran into the same crash.
When saving a STEP AP203 file without specifying the author/organization, OCCT uses the computer's IP address as the default value. This function (OSD_Host::InternetAddress) segfaults, crashing the program.
I've notified OCCT upstream
