texlive doesn't seem  to be the right list really as any bug needs to
be fixed upstream rather in the texlive distribution
however it looks like a bug in acronym, introducing a breakpoint
between its file writing operations:

if I add the following to your testfile which removes \hskip\z@ then
your example works as expected with the m flush to the right margin.


\renewcommand*{\@acf}[1]{%
    \ifAC at footnote
       \acsfont{\AC at acs{#1}}%
       \footnote{\AC at placelabel{#1}\hskip\z@\AC at acl{#1}{}}%
    \else
       \acffont{%
          \AC at placelabel{#1}%
         %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%\hskip\z@
         \AC at acl{#1}%
          \nolinebreak[3] %
          \acfsfont{(\acsfont{\AC at acs{#1}})}%
        }%
     \fi
     \ifAC at starred\else\AC at logged{#1}\fi}
