Circular references in separate files results in stack overflow error #442
Description
Describe the bug
We have an open api specification with circular references where each object is stored in a separate file. This results in a stack overflow error:
runtime: goroutine stack exceeds 1000000000-byte limit
runtime: sp=0x140ade80340 stack=[0x140ade80000, 0x140cde80000]
fatal error: stack overflow
runtime stack:
runtime.throw({0x1048394c0?, 0x104347498?})
I am on the latest version and the pr #418 did not fix the issue for our scenario.
To Reproduce
I've made two example files based on the example files in pr #418:
circular2.yaml
openapi: 3.0.0
info:
