Hi, found out when running the testsuite for elfutils that the following code reproducibly triggers the interrupted system call bug:
#! /bin/sh
echo 'main () { while (1) pause (); }' > native.c
gcc -o native -g native.c > /dev/null 2>&1 &&
{ ./native 2>&1 & native=$! ; } || native=0
kill -9 $native || :
wait $native 2 > /dev/null || :
#> sh ./test.sh
./test.sh: 6: ./test.sh: cannot create /dev/null: Interrupted system
call
HTH!
