            Bug ID: 40144
           Summary: Clang rejects well-formed C99 program using [*] in
           Product: clang
           Version: trunk
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs

Test program (prog.c):

  int main()
    typedef void t(int (*)[*]);
    typedef void t(int (*)[*]);

Compilation command line:

  clang prog.c -Wall -Wextra -std=c11 -pedantic-errors

Observed behaviour:

  The following error message is outputed:

    error: typedef redefinition with different types ('void (int (*)[*])' vs
           'void (int (*)[*])')

Expected behaviour:

  No error message. The two types are equal and not a variably modified type,
  the typeredefinition should be allowed according to the standard.


  gcc does not give any error messages.
