Where does it crash? You need to put in a bunch of printf calls to see where it is crashing. Print the values of the pGVO and paddr pointers with %p.

//----------------------------CODE TO READ GV0 VALUE------------------
static long read_GV0(pGV0)
struct aiRecord *pGV0;
{
long int t;
struct dbAddr *paddr;
t = pGV0->val;
paddr = dbGetPdbAddrFromLink(&pGV0->inp);
dbGet(paddr,DBR_FLOAT,(void *)t,0,1,NULL);
printf("GV0=%ld",t);
return(2);
}
