Tolga HOŞGÖR updated IGNITE-5208:
---------------------------------
Description:
The following segfault happens when:
- using multiple caches (suffixed with number as in X_\{number\}),
- caches contain same type of object but not the same objects,
- doing multithreaded `::Put` operation, only one put is done on each cache
concurrently, independent caches (X_1, X_2, ...) can be operated on and called
`::Put` on concurrently, but that should not be relevant as cache api is thread
safe.
