Use the Perl debugger to figure out exactly where the second-time loading is going wrong. Scanning p5git://perl.c. I see that the debugger is enabled by: 

    PL_perldb = PERLDB_ALL;
    init_debugger();

Since you want more than one interpreter instance per process, then you need MULTIPLICITY defined (as you do) which means that p5git://grep=PL_perldb gets defined as (vTHX->Iperldb) in p5git://embedvar.h. and init_debugger() actually becomes Perl_init_debugger(aTHX). I'll let you look up how to get vTHX and aTHX defined properly based on the allocated interpreter you have a pointer to.
