I think what you see at revision 158633 is a bootstrap failure due to a missing prototype in optabs.h, fixed with revision 158643. Meanwhile revision 158639 introduced another failure probably on all ppc platforms (pr43858 reported against powerpc-apple-darwin9) and fixed with revision 158898. Meanwhile revision 158896 introduced a new bootstrap failure fixed at revision 158901 for pr43935, but not yet for pr43936!-(regress fails to bootstrap since April 22 10:14: NEW GCC build failure, h...@158635 on native). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43936

For some reason, c-decl.o in stage2 has no debug sections:
There are 16 section headers, starting at offset 0x1fbf8:

--- Comment #11 from jakub at gcc dot gnu dot org 2010-04-29 15:37 --- No, otherwise -fcompare-debug or even the whole bootstrap comparison which compares -g -gtoggle built stage2 with -g built stage3 would fail much more often. Strangely, I saw the comparison failure on the trunk, but when I recompile tree-optimize.o with the stage1 gcc and stage2 flags and stage2 gcc with stage3 flags, it is the same after stripping.

OK if bootstrap passes?
