--- Comment #4 from chenglulu <chenglulu at loongson dot cn> --- (In reply to Thomas Koenig from comment #3) > Is this a target or a libgfortran bug, then? I'm not sure about this either, but if I understand correctly, the u->s in find_file0 should not be modified in this function. I think it's probably a bug in libgfortran. I enabled DEBUG_ASYNC, but there is a lot of printed information that I don't quite understand.
