Root Cause Analysis

The analysis is based on the AddressSanitizer stack trace provided in the GitHub issue. The decNumberCopy function is directly identified as the source of the stack-buffer-overflow. The other functions listed are part of the call stack leading to the execution of decNumberCopy with the problematic input. While decNumberCopy is the most directly vulnerable, the other functions are runtime indicators as they would appear in a profile when the vulnerability is triggered. Since I could not fetch the file contents or commit information, the confidence for functions other than decNumberCopy is medium, as their direct involvement beyond being callers cannot be fully ascertained without code inspection.
