           Summary: SDT V3 fails with structs that are only declared
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: translator
        AssignedTo: systemtap@sources.redhat.com
        ReportedBy: jistone@redhat.com


Using gcc version 4.4.4 20100630 (Red Hat 4.4.4-10) (GCC)

$ cat declared-struct.c
#include <sys/sdt.h>
struct foo;
int main()
{
    struct foo* p =3D 0;
    STAP_PROBE1(test, foo, p);
    return 0;
}

$ gcc -c declared-struct.c=20
declared-struct.c: In function =E2=80=98main=E2=80=99:
declared-struct.c:6: error: invalid use of undefined type =E2=80=98struct f=

I think it's complaining about the "+ 0" math on the argument.  If I cast "=
p"
to a void*, it compiles fine.
