getting segmentation fault on GPU when adding a member

I have a class in GPU side, and in a worker-master dynamic scheme I am running some function in each gpu associated with each ranks (I am using a supercomputer). The problem is I was adding some member to the gpu class before but now when I am trying to add a new member I am getting the following error:

Caught signal 11 (Segmentation fault: address not mapped to object at address 0x19)

Actually I did noting I just add something like double * m_cl_matrix; as a member to the class! Thanks in advance
