--- Comment #2 from Douglas Mencken <dougmencken at gmail dot com> 2011-07-09 17:19:38 UTC --- Tried with gcc-v4.7-20110702, now adding `--enable-stage1-languages=c,fortran' to configure options. Stage1 builds fine (now stage0 compiler is 4.6.1-release), even with fortran enabled. On stage2, the process stops at the same moment as I reported initially. ~/build-farm/_gcc_bootstrap # ls -l prev-gcc/fortran/resolve.o -rw-r--r-- 1 root 0 455536 Jul 9 00:15 prev-gcc/fortran/resolve.o ~/build-farm/_gcc_bootstrap # ls -l gcc/fortran/resolve.o ls: gcc/fortran/resolve.o: No such file or directory I also compared sizes of cprop.o object files on both stages, they do differ very much (files are also uploaded to http://ftp.osuosl.org/pub/manulix/logs+errors/gcc-v4.7-20110702/ ): ~/build-farm # ls -l stage*-cprop.o -rw-r--r-- 1 root 0 959512 Jul 9 10:59 stage1-cprop.o -rw-r--r-- 1 root 0 314088 Jul 9 10:58 stage2-cprop.o I also figured out that gcc/cprop.c file does not exist in GCC < 4.7 source tarballs. So the possible reason for the error may be Steven Bosscher's efforts to split gcse.c --> cprop.c and then "clean it up", which caused this regression. I would be thankful for any response.
