Subject: [Bug c/36849] IMA rejects to merge (function)decls with va_args

------- Comment #1 from pinskia at gcc dot gnu dot org  2008-08-11 00:50 -------
The error message is correct as the function types are not compatible.  If in
fact this is invalid C even though we don't currently diagnostic it without
-combine.

Closing as invalid as -combine is doing the correct job of rejecting this.

No, that is not what the C/C++ standard says about compatible function types.

Yes we could enable this and have -pedantic-error reject it but I don't see why
we should allow this as it is obvious invalid C code.
