Crash on macOS with Apple Silicon during Deduplication Process

[ylluminate]

Environment:

• Installed via Homebrew: rmlint Version: 2.10.2 compiled: Sep 28 2023, "Ludicrous Lemur" (rev unknown)
• OS: macOS 14.3
• Shell: zsh 5.9
• Hardware: MacBookPro18,2 (Apple Silicon: M1 Max)

Description:
I encountered a crash while using rmlint to deduplicate files between two large folders. The process seemed to progress normally but terminated unexpectedly with a malloc error.

Command Executed:

sudo rmlint --keep-all-tagged --must-match-tagged --hidden --no-crossdev --merge-directories --xattr --match-extension --progress --threads=32 /path/to/delete // /path/to/keep

Output and Error:
The operation proceeded without issues initially, traversing and preprocessing files, and matching duplicates. However, either during the script generation or during the "Merging files into directories" stage, rmlint crashed with the following output:
