NULL pointer && sgementation error

[hurry123-hyy]

I run the tilespgemm code in cuda 11.8, platform is RTX 4090, g++ version is 7.3, I met two errors, first one is as follows:

this matrix if from suitesparse, HV15R.mtx, nnz is 283073458.

The second error is sgementation error, detailed information is as follws:

this matrix if from solverchallenge, solverchallenge24_02_A.mtx, nnz is 97535322.

I check the memory space is enough, cuda memory always only used 384MB, PC memory still left a lot.
anybody met the same error? looking forward to your reply, thanks a lot ~
