>Description:
Programs using fputws(3) generate an apparently infinite
number of copies of the string passed to fputws().
The code in src/lib/libc/stdio/fputws.c has no obvious mechanism
for loop termination except in the case of an error. This
appears to be a regression introduced in r187302.
>How-To-Repeat:
The following sample code generates an infinite series of "abc":
#include <stdio.h>
#include <wchar.h>
int main(void)
{
fputws(L"abc", stdout);
putchar('\n');
return(0);
}
>Fix:
Not clear at present.
