It [adds](https://github.com/0xOstium/smart-contracts-threeSigma/blob/audit-feedback/src/abstract/Delegatable.sol#L41-L45) 4 bytes to the result pointer, which may mess up the length of the result variable, see more details [here](https://github.com/sherlock-audit/2023-02-gmx-judging/issues/119). ### Recommendation Don't decode the reason. ### Status Addressed in [#83ee4a7](https://github.com/0xOstium/smart-contracts-threeSigma/pull/58/commits/83ee4a7155e6bfff32fd112d2c4eb3f28ddb73dd).
