Dear maintainer(s),
With a recent upload of eigen3 the autopkgtest of stan-math 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 5.0.1-3
stan-math from testing 5.3.0+dfsg-3
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]. Of course, eigen3 shouldn't just break your autopkgtest (or even
worse, your package), but it seems to me that the change in eigen3 was
intended and your package needs to update to the new situation.
If this is a real problem in your package (and not only in your
autopkgtest), the right binary package(s) from eigen3 should really add
a versioned Breaks on the unfixed version of (one of your) package(s).
Note: the Breaks is nice even if the issue is only in the autopkgtest as
it helps the migration software to figure out the right versions to
combine in the tests.
