           Summary: GCC Produces Invalid Assembly Code from Anonymous
                    Function Syntax
           Product: gcc
           Version: 4.4.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: kerrg@ccs.neu.edu

verbose outpuit from compilation

When compiling the following code:

int main(void)
{
    int (*func)(void *) = ({ int $(int (*x)()) { x(x); }; $($); });
    int x = func(func);
    return 0;
}

GCC compiles it to bad assembly code, causing the following error:
func.s: Assembler messages:
func.s:38: Error: suffix or operands invalid for `call'

The particular problem line is this:
    call    $.1597

I have attached more verbose output.
