+Upstream-Status: Inappropriate [disable feature]
+
+After the commit "tcmode-default: switch to gcc 4.6.0 for x86, x86-64 & arm",
+we got bug 1099 (http://bugzilla.yoctoproject.org/show_bug.cgi?id=1099):
+
+Running "install --stage2=/ssd/boot/grub/stage2 /boot/grub/stage1(hd0)
+     /boot/grub/stage2 p /boot/grub/menu list" failed
+Error 6: Mismatched or corrupt version of stage1/stage2
+
+This turned out to be a gcc's bug. See
+https://bugs.gentoo.org/show_bug.cgi?id=360513
+http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39333
+
+Upstream gcc seems uninterested in the bug, so at present we can disable the
+option as a workaround. Thanks Ryan Hill for the investigation and the
+workaround patch.
