Maybe. It could be something atomic related.
For 14.cc case, replacing locale.o and cxx11-shim_facets.o with
ones from non-LRA build fixes the failure.
For example, std::locale::locale(std::locale const&) is compiled
very differently in LRA/non-LRA builds. Strangely, the problem
can't be reproduced with recompiling these objects with -mlra in
non-LRA builds. The above constructor is compiled to

Perhaps the both codes are ok, though something odd happens
on atomic things anyway.
