           Summary: clang is overly permissive with statement expressions
           Product: clang
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: parser
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: daniel at zuster.org
                CC: llvmbugs at cs.uiuc.edu

clang accepts:
int f0() {
  int x = sizeof( ({ L1: g0(); 10;}) );
  goto L1;

Need I say more?

The sizeof here is overkill, gcc seems to reject all jumps into statement
expressions. A nice tether to the brink of insanity.
