[pkg-boost-devel] Bug#893884: libboost-locale1.62.0: LC_CTYPE overrides value of LC_ALL

[Nicolas Dandrimont]

Package: libboost-locale1.62.0
Version: 1.62.0+dfsg-5
Severity: normal
Tags: upstream

Dear maintainer,

libboost-locale's boost::locale::util::get_system_locale function gets the
system locale using environment variables in the following order: LC_CTYPE,
LC_ALL, LANG.

LC_ALL should have precedence over all other variables, as written in locale(7):

    If the second argument to setlocale(3) is an empty string, "", for the
    default locale, it is determined using the following steps:

    1. If there is a non-null environment variable LC_ALL, the value of
    LC_ALL is used.

    2. If an environment variable with the same name as one of the categories
    above exists and is non-null, its value is used for that category.

    3. If there is a non-null environment variable LANG, the value of LANG is
    used.

I've looked at the upstream history, but this source file has been imported
as-is in SVN 7 years ago and hasn't been touched since, therefore I couldn't
find the upstream rationale for this resolution order.

Thanks for considering this report,
Nicolas Dandrimont
