           Summary: clang incorrectly accepts function returning pointer to
                    vla
           Product: new-bugs
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: new bugs

Testcase:

int a(int b) {int (*c(void))[b];**c() = 2;}

This violates the constraint in C99 6.7.5.2p2 because the function c has
linkage.

gcc also messes this up.

Not that we do much checking at all for this stuff at the moment, but I figured
I should file it so I don't lose it.
