TL;DR: Initial C-only release of BenchGen: a program-synthesis benchmark generator.

Highlights

• C code generator for synthesizing benchmark programs.
• New PATH algorithm and improved path-stack control for more deterministic program structure.
• Removed Dalloc dependency and improved build portability.

Fixes & robustness

• Crash and segmentation-fault fixes.
• Memory-leak fixes during data-structure teardown.
• Improved generator robustness (iteration bounds, var-type checks, loop exceptions).

Known issues

• C-only: multi-language support is on the multilang branch.
