The following patch
Index: gcc/dwarf2out.c
===================================================================
--- gcc/dwarf2out.c (revision 140226)
+++ gcc/dwarf2out.c (working copy)
@@ -139,6 +139,9 @@ dwarf2out_do_cfi_asm (void)

allowed for the bootstrap to complete. The testsuite is still running;
when it's done, I'll submit it to gcc-patches.
