What changes to csound5 are required? Can we begin discussing them?

It seems that the inserter engine of Csound5 uses the same address for 
different formulas, overwriting the contents of the address space of the 
input arguments of opcodes. Since the OpenGL graphic opcodes accesses 
these addresses at moments different than k-cycles (i.e. at its own 
frame-rate), their contents  result corrupted using Csound5, giving 
bogus values.
In the older versions of  canonical Csound this didn't happen, leaving 
the opcode argumens space untouched even at moments different than 
k-cycles, allowing to run openGL without a special space-copying k-rate 
functions for opcode, which would add a lot of overhead..
So what I need is to restore the old behavior in Csound5 (at least for 
an OpenGL compliant csound build, eventually inserting preprocessor 
conditionals).

I didn't find the code that treats this so far. Any suggestion on where 
to find this code?

thanks

Gabriel
