We have solved the problem. Please re-download the code.
The previous code may cause the access out of bounds problem. So we add a simple bound check.

Can you provide the exact X you tested?

I tested some non power-of-2 X, but I see no errors. For example
(base) guyue@server:~/dgSPARSE-Library/example/ge-spmm$ ./spmm.out ../data/p2p-Gnutella31.mtx 143
Finish reading matrix 62586 rows, 62586 columns, 147892 nnz.
Ignore original values and use randomly generated values.
