Segmentation Fault in compiler

[cduck]

Minimum example:

from kirin.prelude import basic
from kirin.dialects import ilist

print('Starting')

try:
    @basic
    def trigger_seg_fault_on_compile():
        def closure(i):
            ilist.map(closure, range(4))
        return closure(0)

except BaseException as e:
    print('Exception', e)  # This line is not run because segfault is not catchable

print('This line is not reached')

% uv run python crash.py
Starting
% echo $?  # Process exited with code 139
139

This code snippet seems to run fine for me. What's the Python version uv uses and what kirin version are you on? Have you tried running it without uv?

In my case, there's no exception being raised though either, so I guess that triggers the segfault?

Apologies. I should have given versions.

Works:

• Python 3.14.2 with kirin 0.22.5
• Python 3.14.2 with kirin 0.22.4
• Python 3.12.11 with kirin 0.22.5
• Python 3.11.13 with kirin 0.22.5

% python crash.py
Starting
This line is not reached

Doesn't work:

• Python 3.10.18 with kirin 0.22.5
• Python 3.10.18 with kirin 0.22.4
• Python 3.10.17 with kirin 0.22.5

% python crash.py
Starting
zsh: segmentation fault  python crash.py
