[HTCondor-users] Operations on classad2.ExprTree(None) segfaulting? (HTC24)

[KÃhn, Max (SCC) <max.fischer@xxxxxxx>]

Hi all,

We are currently preparing to migrate to HTC25 and thus updating our Python binding code. Playing around with the new v2 bindings, I discovered that ExprTree(None) is now a documented thing.

However, it looks like almost all operations on it are segfaulting on HTC 24 (24.0.12 + Py3.9 and HTC24.0.10 and Py3.6). Whatâs the point of that? How do they behave on HTC25, or how are they supposed to behave?

Cheers,
Max
