Multithreaded applications no longer crash when calling dprintf() and fork() concurrently
Multithreaded applications that use the dprintf() and fork() *glibc* functions concurrently could previously terminate unexpectedly with a segmentation fault. With this update, the fork() implementation has been fixed to ignore temporary streams created by dprintf(), and the described problem no longer occurs.
