I cannot even reproduce this on the FSF released GCC 6.3.0 code ...

I took me a while to find a platform of mine where I got this error.
Right now it happens here as well:

Let me see if I can reproduce it on aarch64. It might be some bug in the hand
vectorized code.

I can reproduce this with the system compiler (GCC 7) on an arm-linux-gnueabihf
host FWIW. Trying with a trunk build now

Confirmed on trunk with an x86_64-linux-gnu -> aarch64-linux-gnu cross. Here is
a backtrace:
