Misaligned Shared or Local Address

[GoogleCodeExporter]

I have some code written which fails with a thrust::system::system_error

After trying to debug it for a few days i upgraded to CUDA toolkit 4.1
and ran cuda-memcheck

I get the following error:

terminate called after throwing an instance of 'thrust::system::system_error'
  what():  unspecified launch failure
========= Error: process didn't terminate successfully
========= Misaligned Shared or Local Address
=========     at 0x00002bc0 in 
/usr/local/cuda/include/thrust/iterator/detail/zip_iterator_base.h:277:thrust
=========     by thread (64,0,0) in block (12,0,0)
=========
========= ERROR SUMMARY: 1 error

I googled around and didnt find anything mentioning this issue. Is it possible 
this is a Thrust bug?

Also I am running on Ubuntu 11.04 with a dedicated GTX480 for cuda

Thanks,

Matthias

Thanks for the report Matthias.  If you could you attach a minimalistic program 
(e.g. < 30 lines) that exhibits the problem we'll be able to investigate the 
matter further.

In the meantime, I wouldn't be concerned about the warning unless you're 
getting the wrong results.

This triggers the error for me.

Error only occurs when compiling with 
-encode=arch=compute_20,code="sm_20,compute_20". 

Using CUDA 4.1 and Visual Studio 2010.

Interesting for me its CUDA 4.1 on Linux with the newest driver both on Ubuntu 
11.04 and RHEL 5.something
