            Bug ID: 52301
           Summary: boolalpha seems to ignore output width
           Product: libc++
           Version: 11.0
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: unassignedclangbugs at nondot.org

It seems that the boolalpha fmtflag ignores any specified width. 

Here's a cut/paste from a cut/paste from a cygwin session:

$ cat t.cpp

#include <iomanip>
#include <sstream>
#include <iostream>
using namespace std;
int main(int, char *[])
{
        stringbuf sbuf;
        ostream ostr(&sbuf);
        ostr <<  boolalpha <<  setw(7) << (bool)false;
        string s = sbuf.str();
        cout << "'" << sbuf.str() << "'";
}

$ ./a.out
'  false'

$ clang++ -o a.out -stdlib=libc++ t.cpp
