Starting program: /home/pedro/gdb/mygit/build/gdb/testsuite/gdb.base/foll-vfork
[New process 2497]
I'm the child!
I'm the proud parent of child #2497!
process 2497 is executing new program:
/home/pedro/gdb/mygit/build/gdb/testsuite/gdb.base/vforked-prog
Hello from vforked-prog...
[Inferior 2 (process 2497) exited normally]

Num Description Executable
* 2 <null>
/home/pedro/gdb/mygit/build/gdb/testsuite/gdb.base/vforked-prog
1 <null>
/home/pedro/gdb/mygit/build/gdb/testsuite/gdb.base/vforked-prog
^^^^^^^^^^^^
(gdb)
Note how inferior 1 (the parent)'s executable changed to "vforked-prog" too...
Only the child's executable should have changed in reaction to the exec.
