    Let's try this repo: https://github.com/Tai-e/CVE-2021-44228

    The TFG generated in this repo is complete, as is the TFG I generated in the old version of tai-e (0.2.2), only the above issue occurs in the latest version.

    Thanks for reporting this! This regression was introduced in 0.5.1 by commit f4f1c5d. We鈥檙e already tracking it in #191 and working on a fix.

    As a temporary workaround, you can either revert that optimization or wait for the patch to be merged.
