The Plum Hall test lvs07a/conform/t228.dir/_222612Y41.cpp that exercises the std::money_get facet fails at runtime with the following errors:
The expects whitespace to be optional where the money_base::space specifier appears in the pattern format.
According to [locale.money.get.virtuals] para. 2:
Where space or none appears in the format pattern, except at the end,
optional white space (as recognized by ct.is) is consumed after any
We interpret this to mean that:
- where money_base::space appears in the format at least one space is required, and
- where money_base::none appears space is allowed but not required
but other interpretations may be plausible. Clearly Plum Hall must read it differently. Seems like an issue in the standard. I've posted a question to firstname.lastname@example.org to get a clarification.
