Any ideas?

It works if native atomics enabled. Moving to native atomics will solve this problem automatically.

Fixed in #1103

Native atomics is enabled by default and emulated atomics code is removed. The problem most likely was the *.cl kernel for atomics emulation was not pre-compiled with -g when the debug flag was used it was linking to a binary without debug symbols.

Since, emulation is now removed the problem is no longer reproducible.
