The only difference I see is the expected one: openat fails. I used truss -f ./a.out 2>log to obtain this file, which shows the two pids= in the output. I noticed these are missing from yours: how did you obtain your truss log? Note that simply running ./test.sh works fine as expected. Additional notes: Updating the interpreter to #!/bin/ls -l gives the following: cr-xr-xr-x 1 root wheel 0x6 Nov 3 11:34 /dev/fd/3 So, the file (1) exists, and (2) is readable, so the EACCESS doesn't make sense. Using #!/bin/cat gives the same error as #!/bin/sh. --=20 You are receiving this mail because: You are the assignee for the bug.=
