This is certainly a step in the right direction. However, the proper
value to use for addr_size is the one that comes from the header of
the compilation unit containing the expression. (The fact that
there's no compilation unit associated with the frame information is
an existing problem.)
I had a patch to carry that through from a long while back. A fellow
from Intel has been working on updating it; I've encouraged him to
post it here.
