             Bug #: 53577
           Summary: segmentation fault on syntax error
    Classification: Unclassified
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: ettl.mar...@gmx.de


gcc crashes on following syntactically wrong code:


typedef union U1
{
    int i;
} U2 __attribute__((transparent_union));
static
void foo2(U1) {} static foo(int) foo2(U2) {} void bar2(U1 u1,
        U2 u2)
{
    foo2(u1);
    foo2(u2);
}


I am using gcc version:

$ gcc -v
