printf can cause segfaults on ATI GPU (Defect #233)
In test #232 I ran into problems with printf on the GPU.
Using it caused a segfault if one reused existing binaries.
This was observed in the testkernel in the "stout_smear" test. However, no problem appeared in other kernels like plaquette or polyakov.
I did not go into details of the binary savings and perhaps this problem is not so severe since one wants to use printf rather for debugging, but do you have an idea what could cause it?
