Our FileSystem::fileSystemRepresentation method returns CString() under various error conditions. In most cases, we check for a null return of this method before passing the result on to functions (primarily POSIX routines) that are specified as crashing (or undefined behavior) if given a NULL input. We need to be consistent about checking this return value.

I did a search for instances of 'fileSystemRepresentation', and found that all cases except for SandboxExtension::createHandle were safe. The various POSIX functions called with the result of this function handle null inputs properly.

No changes needed here. A fix for SandboxExtension::createHandle will be landed soon.
