| Description: | Towards the end of ast_careful_fwrite(), and attempt is made to flush the userspace buffers using fflush.
If fflush first returns EOF/EINTR, and then returns EOF/SUCCESS, errno is not reset on the second time around the loop, and is then never reset, causing an infinite 100% CPU loop. | ||
