You are right, if you use 2 PV in the cr_route function things will go 
badly.

The reason is that the core function get_str_fparam() returns a pointer 
to a static buffer, and in total there are three(3) static buffers to 
return, so after a fourth call the first value (if cached which is the 
case in your proof) will be overwritten by the fourth. A solution is to 
increase the number of buffers to a number larger than 3 (but still 
small - keep in mind that each buffer is 1kB). I have tested with 6 and 
it works.

Please modify PV_PRINT_BUF_NO in sr_module.c(line 1418) to a larger 
value , compile and retest.

Thanks
