--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> 2013-01-30 17:16:08 UTC --- Created attachment 29308 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=29308 gcc48-pr56154.patch Untested fix, together with guality testcases that show the issue. On x86_64, without the dwarf2out.c change I see with: make check-gcc \ RUNTESTFLAGS='--target_board=unix\{-m32,-m64\} guality.exp=pr56154*.c' Running target unix/-m32 Using /usr/share/dejagnu/baseboards/unix.exp as board description file for target.
