The code below reproduces this error.
This bug should be related to the byte alignment problem.
#include <cblas.h>
#include <stdlib.h>
int main(void){
double *x = malloc(sizeof(double)*5);
double *A = malloc(sizeof(double)*25);
for(int i = 0; i<5 ; i++){
x[i]=i;
}
for(int i = 0; i<25; i++){
A[i]=0;
}
cblas_dsyr(CblasRowMajor, CblasUpper,
5, 1, x, 1, A, 5);
free(x);
free(A);
return 0;
}
Buffer overrun error occurs if the dimension of the Hessian is odd number.
This bug is found on the binary built with OpenBLAS.
