I wonder if this is because on the gimple level we are producing:
_5 = b_3(D) <= 9;
_6 = a_2(D) <= 2;
_7 = _5 & _6;
Now.
Can you add -fdump-tree-optimized=/dev/stdout and provide the output of that

if (v == [] consteval { return std::numeric_limits::max() }()) break;

More generally, you can avoid the linker error if you don't require the symbol
