It seems that issue 2425 has been closed but it should still be opened.

It has been made a duplicate of issue 1800 that is related to error reporting and missing line number.

Go doesn't have support for C style variable argument function so you really

can't call or use vararg C functions in Go program (otherwise what types

should we give them? You could try to give a Go type to C printf function

as an exercise)

cgo program is still a Go program with a magic C import, and as in other

Go programs, every value in it must have valid Go type, so C's varags and

bitfields are not usable (can't even reference them or use a struct that uses

the latter).
