the table has not been initialzed at that stage, you need to force that
yourself, from ch9 of the eagle book:

Finally, if you call I<subprocess_env()> in a void context with no
arguments, it will reinitialize the table to contain the standard
variables that Apache adds to the environment before invoking CGI
scripts and server-side include files:

 $r->subprocess_env;
