It looks like the compiler did loop peeling.  What GCC version is this?
Please try current trunk (to become GCC 10), or at least GCC 9?

It is with GCC 5.5

https://mirrors.edge.kernel.org/pub/tools/crosstool/ doesn't have more 
recent than 8.1

Arnd, can you update the tools?  We are at 8.3 and 9.2 now :-)  Or is
this hard and/or painful to do?

With 8.1, the problem doesn't show up.

Good to hear that.  Hrm, I wonder when it was fixed...
