Bug #: 57021
Summary: Better error message for * missing an expression or
rather using a non-type as a cast
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: [email protected]
ReportedBy: [email protected]
Take:
int main(void)
{
int a;
(a*)0;
}
---- CUT ---
Right now we produce:
t.c:4:6: error: expected expression before ‘)’ token
(a*)0;
^
or for C++:
t.c:4:6: error: expected primary-expression before ‘)’ token
(a*)0;
^
t.c:4:7: error: expected ‘;’ before numeric constant
(a*)0;
^
---- CUT ----
Really we should say instead a is not a type. Yes this is a complex error
recovery issue but I think we should be able to figure it out.
