Greetings! *** Shawn K. Quinn [2021-06-30 18:39]: >(shift count type int, must be unsigned integer) >Should be pretty self-explanatory. Anyone else seeing this? Seems that Go 1.12 can not build that code. I checked with 1.13 -- build fine. I will reflect that minimal version in installation documentation. https://go.googlesource.com/proposal/+/master/design/19113-signed-shift-counts.md Similar issue: https://github.com/minio/md5-simd/issues/17 -- Sergey Matveev (http://www.stargrave.org/) OpenPGP: CF60 E89A 5923 1E76 E263 6422 AE1A 8109 E498 57EF
