Error: Unaligned memory accesses not supported


I have some problem while compiling my CUDA source.
The interesting thing is that it seems to me as if the compiler does not
accept direct relations between the output of an operation and the next
operation. If I try to bring these two operations into a relation, the compiler
gives me the error: “Error: Unaligned memory accesses not supported” but
with reference to another code line which has no effect from these changes.
If i cut the relation between the operations, the source compiles fine …
Also when I get these compiler error, it will work using the -deviceemu parameter…
Is that a compiler bug? :whistling:
Any documentation about this compiler message?
Thanks a lot!
