Just for the benefit of the list: that's fixed now.

I've pushed my work-around as I'm not sure when I'll be able to

That's interesting. Perhaps that could be extended to AArch64 instead
of using the ugly work-around...

Ops, I read too fast yesterday on my phone and I omitted your patch
bound in mail (I thought it was already pushed).

I'm really sorry AS IT FULLY WORKS (including all possible tests).

 

Many thanks.

Thank you Edmund, but it does not work (see below).

 

Btw, do you know that can ask for an account on GCC Compile Farm Project
(see: https://gcc.gnu.org/wiki/CompileFarm)

Here you can have remote access on different machines for free. Among them
you have:
