I find most easy to make child GDB non-interactive.  So that you do not have
to re-enter the exact commands to reproduce the problem each time.  Therefore
use -ex (or -x) for the child GDB:

gdb -ex 'b breakpoint.c:9152' -ex r --args ./gdb ~/t/try5 -ex 'b display' -ex r -ex up -ex b -ex 'info b' -ex 'p/x $pc' -ex 'info line *$pc' -ex 'set confirm no' -ex q -q

Regards,
Jan
