I'm afraid I mis-reduced the issue; try the following (which reproduces on both
trunk r161941 and 4.5.0):

typedef struct LLSModel{
double variance[32];
int indep_count;
}LLSModel;

void av_solve_lls(LLSModel *m, double (*factor)[33], int count, int min_order){
int i,j,k;

for(i=0; i=0; k--)
sum -= factor[i][k];

factor[j][i] = sum;
}
}
for(j=count-1; j>=min_order; j--){
for(i=j; i>=0; i--)
factor[j][i]= 1 / factor[i][i];

m->variance[j]= factor[0][0];
for(i=0; i<=j; i++)
m->variance[j] += factor[j][i];
}
}

This is the same as PR43270 (and the fix for it cures it).
