----------------
??:? _d_assertp [0x4819e9]
/tmp/temp_7FD5CA522650.d:8 _Dmain [0x481918]
error: the process (/tmp/temp_7FD5CA522650) has returned the status 1
(Program-defined exit status)

"/tmp/temp_7FD5CA522650.d:8 " is neither DMD style nor completly GNU style.
There should be a colon after the 8
