static analyzer error in std::sort

I'm getting a static analysis warning on the following code. I don't think it could be my error, but I guess it's more likely a static analysis false positive than a C++ standard library bug. The warning says "Method called on moved-from object of type 'std::basic_string'". Tested in Xcode 26.5 RC. Reported as FB22735405.

#include <algorithm>
#include <string>
#include <vector>

#include <CoreFoundation/CoreFoundation.h>

template <
		class traits = std::char_traits<char>,
        class Allocator = std::allocator<char> >
struct UTF8StringLess
{
	bool	operator()(
		const std::basic_string<char, traits, Allocator>& inFirst,
		const std::basic_string<char, traits, Allocator>& inSecond ) const;
};

template<class traits, class Allocator>
inline bool	UTF8StringLess<traits, Allocator>::operator()(
		const std::basic_string<char, traits, Allocator>& inFirst,
		const std::basic_string<char, traits, Allocator>& inSecond ) const
{
	CFStringRef	theFirst = ::CFStringCreateWithCString( nullptr, inFirst.c_str(),
		kCFStringEncodingUTF8 );
	CFStringRef	theSecond = ::CFStringCreateWithCString( nullptr, inSecond.c_str(),
		kCFStringEncodingUTF8 );
	
	CFComparisonResult	compResult = ::CFStringCompare( theFirst, theSecond,
		kCFCompareCaseInsensitive );
	bool	isLess = (compResult == kCFCompareLessThan);
	
	::CFRelease( theFirst );
	::CFRelease( theSecond );
	
	return isLess;
}


int main(int argc, const char * argv[])
{
	std::vector<std::string> names{ "obey", "Zorro", "can" };
	
	std::sort( names.begin(), names.end(), UTF8StringLess() );
	
	return EXIT_SUCCESS;
