Description:
------------
I often use gdb to debug a failed phpt tests, usually by editing the generated .sh file and prepending "gdb --args" to the command. It is also possible to run gdb directly on the .sh file (setting follow-fork-mode child) but it is less convenient, and also problematic if the test itself forks.

This can be solved by just running the test command with "exec". AFAIK this should be inocuous for regular test running, but quite convenient when running gdb.

Test script:
---------------
gdb --args bash tests/failing_tests.phpt

Expected result:
----------------
gdb running normally

Actual result:
--------------
gdb debugging the parent bash process instead (by default)
