To avoid the confusion with the `env` fork/exec without worrying about
`set follow-fork-mode child` the following might be better:
gdb \
--init-eval-command="set environment LD_PRELOAD=/home/mahmood/foo.so" \
--args /home/mahmood/program/run /home/mahmood/p2/bin/p2 -config t.txt
This commands gdb to set the environment in the child before the child is loaded
All the Best
