Do you have more details about this failure? Does it happen in our
autobuilders? In which context?

We need all patches to have a description and a Signed-off-by line.
Also, they should ideally be upstreamable, which is not the case here.

Could you work on an improved version of this patch, with some more
extensive description, and hopefully a solution that can be accepted by
upstream gcc ?

Best regards,

Thomas
