parameters in the body of a block.
This fixes a bug where clang would materialize the default argument
inside the body of a block instead of passing the value via the block
descriptor.
For example, in the code below, foo1 would always print 42 regardless
of the value of argument "a" passed to foo1.
void foo1(const int a = 42 ) {
auto block = ^{
printf("%d\n", a);
};
block();
}
