How can I retest buildkite?

[wilzbach]

You need to be part of the Buildkite D team (otherwise there's only the old commit --amend trick). I just restarted it for you, but if you ping me on Slack with your email, I can add you to Buildkite. Of course, traditional mail instead of Slack works too.

[kubo39]

Thanks!

[wilzbach]

Restarted it again as Baszile has removed his GitHub account and his packages are no longer available.

[WalterBright]

Given that you found this bug in Phobos, their may be more lurking. Please grep and check all instances of malloc, calloc and realloc.

[CyberShadow]

Sorry, why were the local imports moved to a global import? I think that's opposite to current Phobos policy.

[kubo39]

I didn't care about, thank you for remind! Fixed at #7150
