          Issue ID: 17646
           Summary: dmd segfaults on missing foreach body in import
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: major
          Priority: P1
         Component: dmd

$ cat ut.d
int main()
{
        runTests!"";
}

int runTests(Modules...)() {
        import reflection;
        allTestData!Modules;
}

$ cat reflection.d
struct TestData {} const(TestData)[] allTestData(MOD_STRINGS...)()
{
        foreach (i; MOD_STRINGS)
}
$ gdb -q dmd
Reading symbols from dmd...done.

reflection.d(4): Error: found '}' instead of statement

Program received signal SIGSEGV, Segmentation fault.

(gdb) p fs._body
$1 = (ddmd.statement.Statement *) 0x0


For some reason semantic is going ahead despite syntax having failed?
