With a commit in the range 132503:132513, gfortran.dg/streamio_11.f90 gfortran.dg/streamio_3.f90 and gfortran.dg/streamio_4.f90 started to fail, besides the new test gfortran.dg/streamio_15.f90. The failure is just a call to abort. The patch exposing the failure seems to be <http://gcc.gnu.org/ml/gcc-patches/2008-02/msg00814.html>. There's analysis in the follow-up message in <http://gcc.gnu.org/ml/gcc-patches/2008-02/msg00901.html>. To wit, it seems like one or more bugs in libgfortran/io/unix.c:fd_truncate.
