Hi, we've found a bug in the ksh. It's related to bug that was already reported:
http://www.mail-archive.com/[email protected]/msg00630.html seems there was used something like simplified version of the patch pasted in the mailing list which fixed reproducer pasted there. However this does not seem enough, because following reproducer makes ksh hang in the loop and segfault because of stack overflow: ksh -c 'trap "touch abc" 2 13 ; echo "blah 1" ; usleep 10; echo "blah 2"; usleep 10' | head -n 1 This pattern is repeated in the backtrace: sh_exec -> sh_chktrap -> sh_trap -> sh_eval -> sh_exec ... When complete patch from the mailing list is used, everything works.
