[i386] Numeric literal 0x2000000000000000_usize out of range in tests #1879
Description
On the i386 (32-bit x86) architecture, the size of usize in Rust is 4 bytes (32 bits)
https://github.com/rust-bakery/nom/blob/main/tests/issues.rs#L145
I proposed a patch for Debian to make the test pass. But I'm not sure it's correct.
