The memory is used after released ??

[QiAnXinCodeSafe]

Hi all,
This is Qianxin CodeSafe Team, we found a suspicious issue, at

leveldb/util/cache.cc

Line 316 in 23e35d7

return e != nullptr;

Element "e" is used at

leveldb/util/cache.cc

Line 314 in 23e35d7

Unref(e);

however，function “Unref” is defined at

leveldb/util/cache.cc

Line 226 in 23e35d7

void LRUCache::Unref(LRUHandle* e) {

where has freed e's memory

[somehibs]

e is not de-referenced, so any freed memory is not used. The return usage signals that the if condition was entered during FinishErase.
