This fix seems correct to me, the poly types are not strings. Looking at
other uses of TYPE_STRING_FLAG this change doesn't seem like it would have
impact on parsing or code generation.
OK for trunk.
I committed this in r263561.
happens on arm too.
Same as r263561, but for arm: avoid compilation errors caused by poly
initializers getting treated as string literals.
Tested on arm-none-linux-gnueabihf.
