Kustomize hangs on replacements with regex key-value pair and create: true

[sfbahr]

What happened?

kustomize build or kubectl kustomize both hang indefinitely

What did you expect to happen?

Resources are output with correct replacements

How can we reproduce it (as minimally and precisely as possible)?

I've recreated this with a minimal repo here: https://github.com/sfbahr/kustomize-replacement-bug/tree/broken

The key pieces of config are:

replacements:
- targets:
  - fieldPaths:
    - spec.containers.[name=^logshipper$]
    options:
      create: true

Expected output

apiVersion: v1
kind: Pod
metadata:
  name: nginx
spec:
  containers:
  - image: nginx:1.14.2
    name: nginx
    ports:
    - containerPort: 80
  - command:
    - sh
    - -c
    - tail -F /opt/logs.txt
    image: alpine:latest
    name: logshipper
    restartPolicy: Always

Actual output

None

Kustomize version

v5.5.0

I tested this on a Mac OS v15.1.1, installed Kustomize v5.5.5 using brew install and it runs fine and produces the expected output.

What Linux Distro and version were you using?
