Description
(1) When processing the return value of read, write_fast catches errors, while write_lines silently swallows them. This results in normal return even if read fails.
(2) During writing, the execution result of write is captured in some places while unwrap() is directly called in others, which may trigger an abort when writing fails.
Test / Reproduction Steps
It is triggered in extreme cases where read/write operations fail.
Impact
When a read error occurs, the error is silently swallowed; when a write error occurs, it triggers a crash.
