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. >Release-Note: >Audit-Trail: >Unformatted:
