did a small test program

in compiler Rev 5.036, the two testpointer 1+2 have the highbyte zero,
but should be 0x3F. LowByte i correct - verified with program memory
The testpointer3 to a int32 in rom is ok.

Direct access on the Data via Index is ok too - but i need pointer to switch Data

This worked in 5.012 - maybe the declaration of ROM data must be changed ?

Code:
#include <16f1788.h>   

#device *=16
#device ICD=TRUE
#DEVICE PASS_STRINGS=IN_RAM      
#fuses NOWDT,NOPROTECT,NOLVP, NOPUT
#use delay(internal=16000000)

int32 rom myConst =123456;
char rom Data1[] = {7,8, 9,10, 11,};
char rom Data2[5] ={20,21,22,23,24,};

void main()
{
   int8 dummy=0;   

   rom char *testpointer1 =&Data1[0];
   rom char *testpointer2 =&Data2[0];
    rom int32 *testpointer3 =&myConst;

   char d0 = Data1[0];
   char d1 = Data1[1];
   char d2 = Data1[2];
   char d3 = Data1[3];

   char e0 = Data2[0];
   char e1 = Data2[1];
   char e2 = Data2[2];
   char e3 = Data2[3];

   //dummy to set a breakpoint
   dummy=1;

   char c0 = &testpointer1++;
   char c1 = &testpointer1++;
   char c2 = &testpointer1++;
   char c3 = &testpointer1++;

   //dummy to set a breakpoint
   dummy=2;
   
}
