Hi, There is a [bug report about a build time test with Python3.{13,14}](https://bugs.debian.org/1123268). You can find a [full test log in Debian CI](https://ci.debian.net/packages/p/python-memory-profiler/testing/amd64/68987601/). Here you can find a [patch for the said problem](https://salsa.debian.org/science-team/python-memory-profiler/-/blob/debian/master/debian/patches/0004-Fix-Test-using-Python3.13+14.patch?ref_type=heads). Hope this helps, Andreas.
