I first did a complete rebuild with --enable-debug turned on and all
went fine, no crash.
Then I did a complete rebuild with --enable-debug turned off and it
failed CppunitTest_basic_enable with segmentation fault.
So I turned on --enable-debug again, set export CPPUNITTRACE="gdb
--args" and did only make CppunitTest_basic_enable
The gdb session gave that:
