Another case. Compile with:

cc1 -O3 -march=i686 -g tree-eh.i


-    2fb6:      sub    $0xdc,%esp
+    2fb6:      sub    $0xcc,%esp

[...]

-    38f2:      mov    $0x1,%edi
-    38f7:      movb   $0x0,-0x98(%ebp)
-    38fe:      mov    %edx,-0x9c(%ebp)
-    3904:      cmp    %eax,(%ecx)
-    3906:      jne    3ad9 <execute_cleanup_eh+0xb29>

[...]

+    38f2:      xor    %edi,%edi
+    38f4:      cmp    %eax,(%ecx)
+    38f6:      jne    3ac3 <execute_cleanup_eh+0xb13>
+    38fc:      mov    0x0,%eax
+    3901:      xor    %esi,%esi
