## Problem In multi-character keys, the GIN index creates a CRC Hash of the first 3 bytes of the key. The hash can have the first bit to be set or unset, needing to have a consistent representation of `char` across architectures for consistent results. GIN stores these keys by their hashes which determines the order in which the keys are obtained from the GIN index. By default, chars are signed in x86 and unsigned in arm, leading to inconsistent behavior across different platform architectures. Adding the `-fsigned-char` flag to the GCC compiler forces chars to be treated as signed across platforms, ensuring the ordering in which the keys are obtained consistent. ## Summary of changes Added `-fsigned-char` to the `CFLAGS` to force GCC to use signed chars across platforms. Added a test to check this across platforms. Fixes: https://github.com/neondatabase/cloud/issues/23199
