Dear maintainer(s),
With a recent upload of eigen3 the autopkgtest of pybind11 fails in
testing when that autopkgtest is run with the binary packages of eigen3
from unstable. It passes when run with only packages from testing. In
tabular form:
pass fail
eigen3 from testing 3.4.0-1
pybind11 from testing 2.7.1-1
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 of eigen3 to testing
[1]. Due to the nature of this issue, I filed this bug report against
both packages. Can you please investigate the situation and reassign the
bug to the right package?
