--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
This can only uncover another pre-existing issue as it is a 100% obvious fix. 
I do not have a good way to run anything on arm so please help me spot the
wrong-code in the assembler output.

TBAA issues are also often exposed by scheduling so please try
-fno-schedule-insns[2] or -fstrict-aliasing with -O1.

-Updating SSA information for statement MEM[(struct function *)&D.43856 + 4B] =
__f$__dummy_a;
+Updating SSA information for statement MEM[(struct __lambda0 *)&D.43856] = 

this might also very well be a C++ FE issue.
