[Valgrind-users] Is --trace-children=no functioning? (And, exec of set-user-id programs)

[Tom T. <Tom...@sa...>]

[Hmm, looks like I didn't include the test pgm the first time]

Consider the test program "fe.c" below.  If I do cc -g fe.c and then  =
valgrind --trace-children=3Dno a.out

        =3D=3D4014=3D=3D Conditional jump or move depends on =
uninitialised value(s)
        =3D=3D4014=3D=3D    at 0x40063D: main (fe.c:12)

This is inside the child!  Is that appropriate?

What I am really trying to do is exec a set-user-id program.  Currently =
valgrind fails with EACCES but I prefer that it instead print a warning =
and then just exec the program untraced (which is what "truss"-type =
commands do).

Thanks much for considering this,
Tom Truscott
