[Bug c++/85732] New: use_facet>(mylocale) retrieving wrong locale information
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85732 Bug ID: 85732 Summary: use_facet>(mylocale) retrieving wrong locale information Product: gcc Version: 6.4.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: gnu-org at bignm dot com Target Milestone: --- Created attachment 44110 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=44110&action=edit Source code and test output results showing error Dear Bug Team, I just recently upgraded using "apt" my Ubuntu 16.04 system and gcc was upgraded from 6.2.0 to 6.4.0 which introduced the following bug. In the attached archive is a program "testlocale.cpp" which requires only gcc-supplied header files. The command line to compile it and execute it is in the comments at the top of the file. In essence, it tests each facet of three locales (on my system "en_US.utf8", "pt_BR.utf8" and "C" locales. All worked perfectly in g++ 6.2.0. As of g++ 6.4.0, all of the facets, except the "moneypunct" facet work properly (see line 134). Here is my information: Linux version $ uname -a Linux asusubuntu16 4.13.0-41-generic #46~16.04.1-Ubuntu SMP Thu May 3 10:06:43 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux Compiler version $ gcc --version gcc (Ubuntu 5.5.0-12ubuntu1~16.04) 5.5.0 20171010 Copyright (C) 2015 Free Software Foundation, Inc.

Compile command: $ g++ -std=c++14 -m64 testlocale.cpp -static -o testlocale Run command: $ ./testlocale > testlocale.out Attached is a test output generated by gcc 6.4.0 on my system. Of course, you can test it on your system yourself and try to duplicate the error. Best regards, Tom Straub

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85732 --- Comment #5 from Tom Straub --- Hi Johnathon, Okay, thanks for confirming. I didn't realize it was such as old bug. You're right, I just recently switched over to using -static (got tired of the library mismatches with multiple gcc versions on my system). Best, Tom

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63776 --- Comment #6 from Tom Straub --- Hi Tim, After banging my head against the wall looking for a solution to the C++11 UTF-8 support problems, I finally found what seems to be a great addition to my project, which I think might be beneficial to GNU as well. It is the UTF-8 CPP code. It is implemented as a header file, so there are no linking issues involved. It seems to add all the functionality needed that seems to be missing in GCC currently. The project can be found at: http://sourceforge.net/projects/utfcpp/ It would certainly make implementation of the codecvt stuff less painful. Best, Tom

Bug ID: 63776
Summary: [C++11] Regex collate matching not working
Product: gcc
Version: 4.9.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: gnu-org at bignm dot com
Created attachment 33919
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=33919&action=edit
Full test program source code
The locale has been set to "pt_BR.UTF-8" and the following String should match
the Regexp passed to the group_regexp() function. It seems as if the collation
matching is not working.
String = "João Méroço"
DEBUG: group_regexp(): Using 'c' flag
DEBUG: group_regexp(): Using 'o' flag
DEBUG: group_regexp(): Match Failed!
group_regexp('/("[[:alpha:][:space:]]+")/co') returned failure!
Full test program source code is attached below.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63776 --- Comment #2 from Tom Straub --- Hi Tim, Okay, a program very similar to this using the Boost REGEX library and ICU 4.55 works just fine with this. According to my understanding, the "char" data type and "std::string" classes were specifically set up in C++11 to handle UTF-8 sequences. The "sequence of bytes" are actually valid UNICODE characters. So, there should be no problem, that is, if the std::regex_constants::collate flag is actually working, since the application is using and setting the std::locale to "pt_BR.UTF-8" (which is supported on my box). It is acting as if it is still in POSIX or C locale, since it doesn't recognize the accented characters as "[:alpha:]" class.
