I forgot to include the following bits in the commit log - it's in the ChangeLog and in the commit: > 2012-03-29 Tobias Burnus <bur...@net-b.de> > > PR fortran/56737 > * io/format.c (parse_format_list): Also cache FMT_STRING. > (parse_format): Update call. So far, the issue is fixed on the trunk and the 4.7 and 4.8 branches; GCC 4.7.3 is scheduled to be released in the next days. (Backporting to 4.6 is still pending.)
