odd segmentation fault occurence

Hey guys, Purely to help me debug my code i wondered if i could get some help. I have a function that returns void and in no way accesses memory. However, upon leaving that function i get a segmentation fault. Im not using pointers, not in a loop. The function simply copies data from one array to another and then manipulates that data. So why might i get such an error upon leaving the function and not during?

If putting up the code helps then request it, but really I just want to no why this may happen.

This might have a bazillion of reasons. A look at your code would really help.

segmentation faults can occur long after (relatively) a memory violation has occured in your code. search your code for violations (especially for malloc, free and array boundaries).

okies, the code:

Code:

---

void settriangles()
{
float tessellate[12][6]={0};
int copydata=0, trip=0, count;

for(count=0; count<13; count++)
        {
        if(print[count][S]==1)
                {
                tessellate[count][X]=print[count][X];
                tessellate[count][Y]=print[count][Y];
                tessellate[count][R]=print[count][R];
                tessellate[count][G]=print[count][G];
                tessellate[count][B]=print[count][B];
                copydata++;
                }
        }

copydata-=3;

for(count=0; count<=copydata; count++)
        {
        trip++;
        triangle[trip][X1]=tessellate[0][X];
        triangle[trip][Y1]=tessellate[0][Y];
        triangle[trip][R1]=tessellate[0][R];
        triangle[trip][G1]=tessellate[0][G];
        triangle[trip][B1]=tessellate[0][B];
        triangle[trip][X2]=tessellate[count+1][X];
        triangle[trip][Y2]=tessellate[count+1][Y];
        triangle[trip][R2]=tessellate[count+1][R];
        triangle[trip][G2]=tessellate[count+1][G];
        triangle[trip][B2]=tessellate[count+1][B];
        triangle[trip][X3]=tessellate[count+2][X];
        triangle[trip][Y3]=tessellate[count+2][Y];
        triangle[trip][R3]=tessellate[count+2][R];
        triangle[trip][G3]=tessellate[count+2][G];
        triangle[trip][B3]=tessellate[count+2][B];
        }

printf("\nPre Split\n");

for(count=0; count<=copydata; count++)
        {
        if(triangle[count][Y1]!=triangle[count][Y2] || triangle[count][Y2]!=triangle[count][Y3])
                {
                trip++;
                printf("\nSplitTriangles called\n");
                splittriangle(count, trip);
                }
        }
       
printf("\nLeaving SetTriangles\n");

return;
}

thats the function, when ran it goes as far as printing "Leaving.." etc then when it returns to the main, it has a segmentation fault

i wondered about it overwriting the address stack as you said, the code is pretty useless on its own, i'll just have to dry run i guess. I just wondered if it was likely to be me overwriting data, cheers guys :)

damn you guys are good ;) thanks for the array thung that does appear wrong.
XYRGBS are an enumerated types used to store the values coords x,y with colour RGB and the S is used in a different function to see whether it needs to be used or not.
Im not too sure about structures so I was doing it that way until i find time to look into them a bit better. Thank you :)

*does happy dance* fixed it! ty very much. i have another error, so be expecting another post in a few hours if i cant sort it :P
