Memory error in G_matrix_inverse

[stopkovae]

Hi,

I would like to ask for error correction in G_matrix_inverse() function. It makes "free(): invalid next size (fast)" error.

I suggest replacing of

perm = (integer *) G_malloc(wmat->rows);
with
perm = (integer *) G_malloc(wmat->rows * sizeof(int));

in grass/trunk/lib/gmath/la.c (line 486).

Thank you in advance.

Eva
