Segmentfault 0 - s3fs 在 CentOS 9 上崩溃

<!-- -------------------------------------------------------------------------- My application uses PHP 8.2.31 and Apache. I create a folder in the S3 mount point, write a file, and then delete the folder, causing the service to crash. I identified that my application was not calling fclose before rmdir. I fixed the application, but I thought it would still be worth reporting that s3fs crashes in this situation.
