zstd: Disable extended memory copies (amd64)#644
Merged
Conversation
Using longer memory copies leads to rare, random crashes with fuzz testing. It is therefore disabled for now.

BTW, do you think it would be easy to overallocate buffers? I mean make sure we have always a few spare bytes to always use the fast copy routine. |

@WojciechMula #645 may be the real crash. We don't control all allocs, and if a destination buffer is provided we don't really want to reallocate just to have a few extra bytes. For now |
