Maybe a logic error in buckets/deflate_buckets.c at line 207?
It's running a beta copy of Apple MacOS 10.11 (Big Sur) on AMD hardware. But
I've compiled 100's of open source packages in the past few days, and it's the
first time I've seen this, so it's probably worth a closer look by someone more
familiar with the code than I am.
I've listed the priority as Major, because I'm not sure the impact on the code
at execution. Theoretically the bug could be a higher or lower priority.
