TEST_SUBJECT="truncate EFAULT"
. test_prelude
fmt > test.ok << 'fubar'
truncate(pathname = 0xNNNNNNNN, length = 123) failed, Bad address (EFAULT)
because pathname refers to memory that is outside the process's accessible
address space; this is more likely to be a software error (a bug) than it
is to be a user error
