<pre>Trying to construct an object in the expression parser doesn't seem to work on
Windows.
Simple reproducer is in
test/commands/expression/ignore-artificial-constructors:
```
struct Foo {
// Triggers that we emit an artificial constructor for Foo.
virtual ~Foo() = default;
};
int main() {
Foo f;
// Try to construct foo in our expression.
return 0; //%self.expect("expr Foo()", substrs=["(Foo) $0 = {}"])
}
```
This fails on Windows with the following error:
```
AssertionError: False is not True : Command 'expr Foo()
Error output:
error: The expression could not be prepared to run in the target
' returns successfully
```</pre>
