gitbw95 f060b47ee8 Fix the segdefault bug in CompressedSecondaryCache and its tests (#10507)
Summary:
This fix is to replace `AllocateBlock()` with `new`. Once I figure out why `AllocateBlock()` might cause the segfault, I will update the implementation.

Fix the bug that causes ./compressed_secondary_cache_test output following test failures:

```
