In many places checking for nullptr is done using EXPECT test macros
that doesn't return from the function when condition is not met
(i.e. they are non-fatal). Lack of further error handling results
in a subsequent segfault. To avoid that in most places it's sufficient
to change macro type to ASSERT.
