Description Dmitry V. Levin 2004-12-19 23:51:33 UTC 
Description of problem:
strace -i produces unwanted warning and invalid value for instruction
pointer during first execve call.

Version-Release number of selected component (if applicable):
strace-4.5.8

Steps to Reproduce:
Actual results:
$ env -i strace -i /bin/true
upeek: ptrace(PTRACE_PEEKUSER,12345,48,0): No such process
[????????] execve("/bin/true", ["/bin/true"], [/* 0 vars */]) = 0
[08048080] _exit(0)

Expected results:
$ env -i strace -i /bin/true
[001b86f8] execve("/bin/true", ["/bin/true"], [/* 0 vars */]) = 0
[08048080] _exit(0)

strace-4.5.8-alt-fake_execve.patch

Proposed patch.

Side effect of this solution is that execve syscall will be always included
into the "strace -c" statistics.
Comment 2 Roland McGrath 2005-02-06 01:17:44 UTC 
I've put the patch in.
