Do you have any patch which would help me reproduce the issue? The v3 tree currently lacks a target using the code in question.
Not at all. Just build the Qemu target with a freshly checked out tree and an official version of binutils from gnu.org
By the way, IIRC Segher once wrote that binutils from gnu.org are a completely different beast compared to "linux binutils" shipped by almost all distributors.
Not a "completely different beast", but please do us a favour and try with FSF binutils before reporting problems :-)
