This happens when the function findchild() running from wait_child() is interrupted by sigchild() running findchild() again. This happens when the child started just before exits too quickly. >How-To-Repeat: >Fix: In popen.c (functions free_child() and wait_child()) the line struct child *cp = findchild(pid); must be moved after the 3 sigfunction-calls. >Release-Note: >Audit-Trail: >Unformatted:
