--- Comment #8 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- > The dump-ada-spec-2.C had failed with my local change (C++ flexible arrays > change from 'array(0 .. -1)' to 'array(size_t)'; I expect the latter is more > correct). While reproducing the failure, I used the option on the command > line. Then, while reproducing another failure in nsdmi-union6.C, I > accidentally used the same option again and stumbled into the failure. I see, thanks. We tried very hard to come up with a name that couldn't be typed inadvertently but we are obviously outsmarted by a simple shell. ;-)
