out-of-bounds array access

[g2721]

In the Inverse function there is a out-of-bounds array access that may cause hard faults on embedded hardware.

In Lapack/Src/dgetrf.c towards the end of the file the following loop will run for one to many iterations. (I.e. beginn and end at the wrong index)

    for(int i = 1; i <= min(*m, *n); i++)
	IPIV_d[i] = (double) ipiv[i];

Example if Matrix size is 9x9 min(*m, *n) will be 9.
ipiv[i] and IPIV_d[i] will have a length of 9 each. Meaning they should be accessed from [0] to [8]. Instead [1] to [9] is used.

Fix should most likely look like this:

for(int i = 0; i < min(*m, *n); i++){
	IPIV_d[i] = (double) ipiv[i];
	}

I've encountered this issue as well. It occurs in debug mode under the ARM system, but it doesn't exist in release mode. The error is "Segmentation fault (core dumped)".
