Block compression incompatibility with C/Python library about lz4 HOT 4 CLOSED

This is definitely a bug, thank you for reporting and providing a reproducer.
I will have a look and try to fix it asap, unless you beat me to it ;).

from lz4.

Here are my findings:

• the go package can compress/uncompress your sample string just fine
• same for the C version of lz4 (*** LZ4 command line interface 64-bits r128, by Yann Collet (Apr 3 2018) ***)
• python with module lz4 at 2.2.1 fails with the error message you mention

Maybe worth checking with the maintainer of the python package maybe?

Thanks for investigating this! I've opened a case with the Python lib and we'll see where it goes.

It could be that mfLimit should be adjusted.

Does the error still happen if you change this line to mfLimit = 8 + minMatch + 2
