 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);''[[BR]]
 with[[BR]]
 ''perm = (integer *) G_malloc(wmat->rows * sizeof(int));''

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

 Thank you in advance.

 Eva
