Invalid Address

I am running my program in release and debug mode and it runs properly. However, when I run my program in cuda-debugging mode I get the following message:
error MemoryChecker: #misaligned=0 #invalidAddress=240 (No other messages - out of bounds or illegal address)
The documentation explains what does illegal address mean. However, for the invalid address gives the following explanation:
This occurs when any thread within a warp executes an instruction that accesses a memory space not permitted for that instruction.
The above message seems to be a hardware issue?

it is ok

Thank you!!! Can you please elaborate more on this issue.
