using a literal implies 32-bit integers for some compilers so this could overflow potentially.

Does this correspond to a OSS-Fuzz regresion?

As it was explained to me, part of the seed corpus comes from the fuzzer binary itself (if I had to guess it swaps random bytes from it) so there is small chance of exposing internal library information if we shared the file.

Ah, thank you. Does it work differently from OSS-Fuzz, or use a different seed corpus?

It was found with our internal fuzzer. Unfortunately do to how it works there are concerns over sharing the actual file.
