Hi, I've run the unit tests for pypy and pypy-stackless on FreeBSD and at some stage the tests causes pypy(-stackless) to core dump. Here are the results: # pypy1.5 -c "from test import testall" <snip/> test_capi internal test_L_code internal test_broken_memoryview RPython traceback: File "implement_3.c", line 63565, in _PyObject_New File "implement_3.c", line 65132, in _PyObject_NewVar File "implement_3.c", line 31701, in from_ref Fatal RPython error: AssertionError Abort (core dumped) # pypy-stackless1.5 -c "from test import testall" <snip/> test_capi internal test_L_code internal test_broken_memoryview RPython traceback: File "implement_1.c", line 241860, in _PyObject_NewVar File "implement_1.c", line 165468, in from_ref Fatal RPython error: AssertionError Abort (core dumped) Is there any other debug information needed? And how can I help fix this? Also, how would one run the unit tests under sandbox? Regards, David
