Robert Dubner <rdubner at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |FIXED Status|UNCONFIRMED |RESOLVED --- Comment #4 from Robert Dubner <rdubner at gcc dot gnu.org> --- Sigh. It turns out there is a difference between *> { dg-output-file "m4.out" } and *> { dg-output-file, "m4.out" } The difference is that the second one, after the successful run of the program, just silently does...nothing. The most wonderful thing about this effort is the incredible richness of new mistakes I can make! Thanks!
