Are automatic variables (that are defined in functions, lambdas, blocks)
in C++11 thread local? Is the following code correct:
auto f1 = [&](const double x) {
double y = sin(x);
SomeClass1 obj1;
double z = obj1.f2(y);
return cos(z);
}
// Some function which creates several threads which call f1.
calculate_parallel(f1);
This should be okay, provided that sin, cos are indeed the global
functions and that SomeClass1 does not touch global state in a
non-thread-safe way. You might want to use [] instead of [&], though.
