Bug#955640: r-cran-uwot: autopkgtest regression: Index size is not a multiple of vector size

Source: r-cran-uwot
Version: 0.1.8-1
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 r-cran-uwot the autopkgtest of r-cran-uwot fails
in testing when that autopkgtest is run with the binary packages of
r-cran-uwot from unstable. It passes when run with only packages from
testing. In tabular form:

                       pass            fail
r-cran-uwot            from testing    0.1.8-1
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?
