On which OS did this happen?

Linux

Reproduction Steps

I've been having a hard time reducing a test case, the test case crashes my remote desktop connection.

Reviewing the code a bit suggests that maybe this line is responsible

			int count = 0, iter = 0;
			while (1) {
				iter++;
				int n = autoname_worker(module, wire_score);
				if (!n) break;
				count += n;
			}

Expected Behavior

Not get stuck in a loop

Actual Behavior

Autoname gets stuck in a loop.
