--- Comment #2 from Bill Schmidt <wschmidt at gcc dot gnu.org> --- I've verified that this only happens with a bootstrapped compiler. A one-pass build does not produce the problem. The output from "cat net/check-testlog" for such a build is: PASS PASS: net Ian, I am not having luck using `make GOTESTFLAGS=--keep net` to reproduce. I guess that I need some flavor of `make check`, but so far my attempts haven't managed to save the a.out file. Any recommendations? I am not sure what command is supposed to build the a.out in question, so I'm at a bit of a standstill.
