Does $cmd work if you paste it into the shell?

Nothing wrong with that subroutine aside from shell interpolation vulnerability, which wouldn't be triggered by these strings (no meta characters) 

 src_line_info(
 '/auto/stbu-tools/wrlinux/wrl6/wrlinux-6/layers/binary-toolchain-4.8-
+39/bin/i686-wrs-linux-gnu-addr2line',
 '/auto/pix-asa-image/essen/9.4.2.11/smp',
);

If $cmd works from shell but not from src_line_info, then other part of program must use setuid to change the user, or the user running the program isn't the same one as your shell
