@smuzaffar could you check if cms-externals/eigen-git-mirror#11 also fixes the problem ?

It would keep Eigen debugging enabled in host code compiled by nvcc.

thanks @fwyzard , cms-externals/eigen-git-mirror#11 hqas fixed the issue.
lets get this in PY312 IBs

[cmsbuild]

This pull request is fully signed and it will be integrated in one of the next IB/CMSSW_16_1_X/py312 IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @ftenchini, @sextonkennedy, @mandrenguyen (and backports should be raised in the release meeting by the corresponding L2)
