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:

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.
