Is there a reason why you are applying this during regression only
fixes? We have been release branch rules for about a month or longer
now and libstdc++ still is getting changes which seems a little big for
a release branch.
There is no release branch.
pb_ds is new code, and I found errors in
the debug parts of it. I don't want to have a release of new code
that has known API issues, and then have to support it. The patch was
larger than I expected but mostly mechanical, and to extensions which
have historically been allowed more leeway.
