Hi Nick,

This is related to https://inbox.sourceware.org/binutils/dcfdca93-1ad8-4c77-9544-b6fa384f1ef6@arm.com/T/#mbfb1eee2e964365e232909a12bf64dacfca27438.
I merged the fix on the branch yesterday -> https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=a69b049d74216b4f24dd10d76b1b461481a58a49
