Summary: Buffer over-read in MurmurHash3_x64_128
Key: DATASKETCHES-5
URL: https://issues.apache.org/jira/browse/DATASKETCHES-5
Project: Apache Datasketches
Issue Type: Bug
Reporter: Csaba Ringhofer
MurmurHash3_x64_128 seems to contain a half-commented-out change that leads to
adding the offset to the key 2 times:
'blocks ' is increased:

but the following lines assume that 'blocks ' still points to the start of the
key:
