alexcrichton opened PR #7559 from alexcrichton:fix-cast to bytecodealliance:main:

This commit fixes a bug in initializing memory segments of 32-bit memories where if the offset was negative when viewed as a signed integer the offset was incorrectly sign-extended to a 64-bit value instead of zero-extended. This commit replaces an i32-to-u64 cast with an i32-to-u32 cast followed by a u32-to-u64 cast which performs the zero extend.

Closes #7558
