Backout

seems to fix this failure.

------- Comment #2 from amylaar at gcc dot gnu dot org  2005-12-13 21:21 -------
Is building a cross-compiler configured with --target=x86-64-elf likely to
work up to this point and reproduce the problem?

I didn't have any luck with either x86-64-elf or x86-64-linux, bfd refused to
build.  So I looked for the latest x86-64 posting to gcc-testresults, which had
x86_64-suse-linux-gnu .  This did actually go on till unwind-dw2.c,
but now I get errors from some header file SNAFU:

could someone send me their x86-64 unwind-dw2.i along with the cc1 flags to
