Douglas Bagnall 637e7cbdba lzxpress: compress shortcut if we've reached maximum length ... A simple degenerate case for our compressor has been a large number of repeated bytes that will match the maximum length (~64k) at all 8192 search positions, 8191 of which searches are in vain because the matches are not of greater length than the first one. Here we recognise the inevitable and reduce runtime proportionately. Credit to OSS-Fuzz.
