test_extrapolator fails with polynomial normalization error

[devin-ai-integration]

Issue Description

During CI builds, test_extrapolator is failing with a polynomial normalization error in Sum.cpp:1478.

Error Message

Need normalized polynomial of f(v8) to get its coefficients

Affected Platforms & Builds

• Windows (MSVC build)
• macOS
• macOS Vcpkg build
• (Pending verification on Windows Vcpkg/Conan builds)

Build Status Pattern

✅ Passing:

• Ubuntu CI
• Docker CI
• Ubuntu Vcpkg

❌ Failing:

• Windows MSVC
• macOS
• macOS Vcpkg

Analysis

• Error occurs in Sum.cpp line 1478
• Issue appears to be with polynomial normalization logic
• Not related to comparison operator changes
• Affects both Windows and macOS builds consistently
• Occurs across different build systems (native and Vcpkg)

Next Steps

1. Investigate polynomial normalization logic in Sum.cpp
2. Review test_extrapolator's polynomial handling
3. Consider platform-specific differences in floating-point handling
4. Analyze build system differences between passing (Ubuntu/Docker) and failing platforms
