The line above that DCHECK sets the minus_zero_value to a new HeapNumber of
value -0.0. It seems like something fundamental is not working in your
environment.
Can you print the values
1) -0.0
2) std::signbit(-0.0)
3) roots.minus_zero_value()->Number()
4) std::signbit(roots.minus_zero_value()->Number())
just before the DCHECK?
The output should be -0.0, 1, -0.0, 1.
E.g.
printf("%f, %d, %f, %d\n", -0.0, std::signbit(-0.0),
roots.minus_zero_value()->Number(),
std::signbit(roots.minus_zero_value()->Number()));
