C++ :: Error Entering A Function?

I have no error compiling, but running my project it stops before entering a function and debugging I have an error about Segmentation fault. The function:

Code:

Mat logGabor(matriz filter,Mat filter,double r_o,double theta_o,double sigma_theta,
matriz radius,matriz theta,int cols,int rows,double sigma_r,int *padSize){
Mat rpad;
int k=*padSize;
printf("Welcome to the function"); //Here the error
...

More info: I created the matriz as : typedef double** matriz;
and a createmat function that give back a double** and in this function I allocate space for matriz and works. In the main:

Code:
Mat chr-Rpad[4][5]; //chrOrient=4;chrScales=5
for(int i_or=1;i_or<chrOrient;i_or++){
for(int i_sc=1;i_sc<chrScales;i_sc++){
//some math calculation
chrRpad[i_or-1][i_sc-1]=abs(logGabor(filter,imftt2,r_o,theta_o,sigma_theta,radius,theta,cols,rows,sigma_r,padSize));
