cffi-1.9.1: segmentation fault during self test on NetBSD
Created originally on Bitbucket by wiz
When running the self tests on NetBSD 8.99.1/amd64, there are segfaults:

*** Error code 139
In total, I have to disable the following tests so that I see now core dumps:
py.test-3.6 -v -k "not test_callback and not test_a_lot_of_callbacks
and not test_wchar and not test_errno_callback and not
test_functionptr_simple and not test_functionptr_voidptr_return and
not test_functionptr_intptr_return and not
test_functionptr_void_return and not test_cast_functionptr_and_int and
not test_structptr_argument and not test_array_argument_as_list and
not test_array_of_func_ptr and not test_function_pointer and not
test_access_callback and not test_win32_calling_convention_0 and not
test_ffi_callback and not test_array_length_from_constant and not
test_some_integer_type_for_issue73"This gives me:
<<<moved 3.6MB of output to dump.txt>>>
This is not the same as #303 (closed); due to changes in NetBSD and libffi in pkgsrc, all self tests for libffi now pass successfully.
Let me know which of the other self tests failures need their own bug reports. Thanks!
