Source: rust-smallvec Version: 1.7.0-1 X-Debbugs-CC: debian-ci@lists.debian.org Severity: serious User: debian-ci@lists.debian.org Usertags: regression Dear maintainer(s), With a recent upload of rust-smallvec the autopkgtest of rust-smallvec fails in testing when that autopkgtest is run with the binary packages of rust-smallvec from unstable. It passes when run with only packages from testing. In tabular form: pass fail rust-smallvec from testing 1.7.0-1 all others from testing from testing I copied some of the output at the bottom of this report. Currently this regression is blocking the migration to testing [1]. Can you please investigate the situation and fix it? More information about this bug and the reason for filing it can be found on https://wiki.debian.org/ContinuousIntegration/RegressionEmailInformation Paul [1]
