Описание
Storage corruption due to variables overwritten by re-entrancy locks
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.
