While building the toolchain's C library, we encounter the assertion `llvm::isUIntN(BitWidth, val) && "Value is not an N-bit unsigned value"'`.
This issue prevents us from bootstrapping the toolchain.
The entire log (including the stage 0 compiler build) is at [build_22.1.0-rc0.log.xz.txt](https://github.com/user-attachments/files/24621852/build_22.1.0-rc0.log.xz.txt), an excerpt is below.
The compiler dumped these outputs:
* [strfmon-aff67a.sh.txt](https://github.com/user-attachments/files/24621889/strfmon-aff67a.sh.txt)
* [strfmon-aff67a.c.txt](https://github.com/user-attachments/files/24621891/strfmon-aff67a.c.txt)
