[LVS _222612Y41] errors on std::money_get extracting space
----------------------------------------------------------

                 Key: STDCXX-767
                 URL: https://issues.apache.org/jira/browse/STDCXX-767
             Project: C++ Standard Library
          Issue Type: Bug
          Components: 22. Localization
    Affects Versions: 4.2.0, 4.1.4, 4.1.3, 4.1.2
            Reporter: Martin Sebor
            Priority: Minor


The Plum Hall test lvs07a/conform/t228.dir/_222612Y41.cpp that exercises the {{std::money_get}}
facet fails at runtime with the following errors:

{noformat}
$ ./_222612Y41

ERROR in _222612Y41.cpp at line 85: "" != "-12345678901234"

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:

{quote}
  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
  required space.
{quote}

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 [mailto:c++std-lib@accu.org] to get
a clarification.
