--- Comment #1 from janus at gcc dot gnu.org ---
I can confirm the leak with gfortran versions 4.7, 4.8 and trunk. However,
there is no leak in 4.3, so it is a regression (haven't tried other versions).

Indeed the dump produced by -fdump-tree-original shows a __builtin_malloc,
which is never freed. The regression seems to be due to this commit:
