Farid Zaripov commented on STDCXX-878:
--------------------------------------
I'm afraid that is not so much time left for 4.2.1 release and possibly this
issue should be deferred until 4.2.2 or even later.
> std::numpunct<>::do_get() extracts too many optional whitespaces leaving none
> for another fields like cukkency symbol or negative sign

> Key: STDCXX-878
> URL: https://issues.apache.org/jira/browse/STDCXX-878
> Project: C++ Standard Library
> Issue Type: Bug
> Components: 22. Localization
> Affects Versions: 4.1.2, 4.1.3, 4.1.4, 4.2.0
> Environment: All
> Reporter: Farid Zaripov
> Priority: Minor
> Fix For: 4.2.1
>
>
> The 22.locale.money.get test fails with number of assertions.
> The failed two checks:
> Here the currency symbol contains space, but it's already extracted while
> processing none pattern.
> {noformat}
> // all spaces extracted since currency symbol (last) is mandatory
> // verify that the facet doesn't extract too many optional spaces
> // leaving none for the final required currency symbol
> TEST (T, 103.0, "103 ", 4, showbase, eofbit, 0, "[EMAIL PROTECTED]", "
> ");
> {noformat}
> Here the negative sign contains trailing space, but it's already extracted
> while processing none pattern.
> {noformat}
> // { sign, value, none, symbol }
> // negative_sign is "- ", (note the single trailing space)
> // verify that the extraction suceeds, i.e., that the money_base::none
> // specifier that's last in the pattern doesn't confuse the facet into
> // extracting all the optional whitespace, leaving none to complete
> // the negative_sign
> TEST (T, -109.1, "-109 ", 6, 0, eofbit, 0, "[EMAIL PROTECTED]", "");
> {noformat}
