Can you reproduce with "-cpu qemu,vx=off" added to the QEMU command
line? Could be some fallout from vector instruction support. Currently
ill, will have a look when I'm feeling better.

Title:
qemu TCG in s390x mode issue with calculating HASH
Status in QEMU:
New
Bug description:
When using go on s390x on Debian x64 (buster) (host) and debian s390x
(sid) (guest) I run into the following problem :
The following occurs while trying to build a custom project :
go: github.com/FactomProject/basen@v0.0.0-20150613233007-fe3947df716e:
Get
https://proxy.golang.org/github.com/%21factom%21project/basen/@v/v0.0.0-20150613233007-fe3947df716e.mod:
local error: tls: bad record MAC
Doing a git bisect I find that this problem only occurs on and after
commit 08ef92d556c584c7faf594ff3af46df456276e1b
Before that commit, all works fine. Past this commit, build always
fails.
Without any proof, It looks like a hash calculation bug related to
using z/Arch vector facilities...
