------- Comment #4 from hjl dot tools at gmail dot com  2010-06-10 23:20 -------
From:

http://gcc.gnu.org/ml/gcc-patches/2010-06/msg01081.html

   if (!df_live_scratch)
-    df_live_scratch = BITMAP_ALLOC (NULL);
+    df_live_scratch = BITMAP_ALLOC (&problem_data->live_bitmaps);
...
+      bitmap_obstack_release (&problem_data->live_bitmaps);

       if (df_live_scratch)
        BITMAP_FREE (df_live_scratch);

We are calling bitmap_obstack_free after bitmap_obstack_release is called.

------- Comment #5 from dominiq at lps dot ens dot fr  2010-06-11 17:48 -------
For the record revision 160549 also broke boostrap on x86_64-apple-darwin10.3.0
near the end of stage 2:


echo CRTSTUFF_T_CFLAGS = '' >> tmp-libgcc.mvars
echo CRTSTUFF_T_CFLAGS_S = '' >> tmp-libgcc.mvars
echo TARGET_SYSTEM_ROOT = '' >> tmp-libgcc.mvars
mv tmp-libgcc.mvars libgcc.mvars
../../work/gcc/config/i386/i386.md: In function 'internal_dfa_insn_code':
../../work/gcc/config/i386/i386.md:358:1: internal compiler error: Segmentation
fault

Since it is now fixed with revision 160612, I don't see the point to fill an
obvious duplicate.
