No, that's what caused this problem. What happens is that you when run a program that uses program_options, the shell unquotes the arguments, so an argument with a space in is not quoted. Then program options calls lexical_cast to convert the argument from a string to a filesystem path. Lexical cast uses filesystem's stream extractor to perform this conversion. But since there's a space, it only extracts part of the file name.
You are describing the behavior w/o the patch applied. With the patch applied filesystem's extractor extracts the whole name until a new line. I see that the patch is already in 1.44. What version do you see the problem in ?
Lexical cast notices that only some of the string has been extracted, realises that something has gone wrong and throws an exception.
There's also a double unencoding issue if the file's name contains quotes.
