Description

I have a copy of the original Collab Subversion repository:

Revisions: 40515
Repository Format: 5
Compatible With Version: 1.6.0
Repository Capability: mergeinfo
Filesystem Type: fsfs
Filesystem Format: 4
FSFS Sharded: yes
FSFS Shard Size: 1000
FSFS Shards Packed: 0/40
FSFS Logical Addressing: no

I can dump and verify this repository with 1.10 using any size of cache but attempting to load the dump into a new repository fails when the cache is greater than 64MB.

svnadmin: E160004: Corrupt node-revision 'rv-1.0.r6752/37'
svnadmin: E160004: Reading one svndiff window read beyond the end of the representation

If I use a small cache I can complete the load. I can also verify the new repository with a small cache, but if I use a large cache the verification fails:

* Error verifying revision 11887.
