This is how I set PETSC_OPTIONS:

 export PETSC_OPTIONS="-start_in_debugger -debug_terminal \"screen -X
-S debug screen\""

I did try using the command line options only (unset $PETSC_OPTIONS
and used a petsc example), and that has the same problem.  If I only
run the command

screen -X -S debug screen redirect.sh gdb

It loads a new window in screen without issue.  So something funky is
happening inside petsc.
