The problem is completely trivial and the attached patch fixes it (wrong line number in one expected result).

This is not failing on our buildbots, so the fix is probably not right. 

Which system are you running on?

Happens when packaging Python 3.10 for openSUSE/Linux.

And no there is no other patch touching pdb (or pdb tests).

Can you give full details of what you're doing?

This looks like a problem on your side. Line 94 is the correct line for the function in 3.10.0 release.

$ git checkout v3.10.0
$ sed -n '94p' Lib/pdb.py 
def find_function(funcname, filename):

Matej, does your build system perhaps strip off the shebang of Lib/pdb.py? That would explain why you are getting the function on line 93.

Yes, that’s it. Thank you.
