    Summary: Storage corruption due to variables overwritten by re-entrancy locks

    Details: ### Background When attempting to use the v0.2.14 release, @pandadefi discovered an issue using the `@nonreentrant` decorator. ### Impact Reentrancy protection storage slots get allocated to the same slots as storage variables, leading to the corruption of storage variables when using the `@nonreentrant` decorator. ### Patches This issue was fixed in v0.2.15 in #2391, #2379 ### Workarounds Don't use the `@nonreentrant` decorator in these versions.
