Hi!

While rebuilding the python related packages against the Python 3.15rc1
version we found that dill causes a bug in other packages (in this case
pylint [1]).

The error is that dill tries to access co_lntab which is removed in
3.15, upstream already has a fix for this [2].

I applied the upstream fix in the sandbox [3] to be able to have working
packages that depend on dill, please consider applying the patch to
support the upcoming 3.15 version.

Happy hacking,

thanks

Hi!

I found another package that is also affected by this issue: lmfit-py.
Rebuilding against the fixed dill version solves it also for that
package.

Please consider applying the upstream patch to solve the problem.

Thanks!
