FreeArc 0.67 + fazip64: Footer corruption when using LZMA via stdin/stdout on Windows
FreeArc 0.67 on Windows 10 produces corrupt archives when using the `fazip64` LZMA compressor via stdin/stdout. The compression appears successful, but subsequent archive testing (`arc t`) fails with a footer decompression error. This issue affects any pipeline using the `lzma` method, which defaults to `fazip64` in `arc.ini`.
