There also was a concern that -fomit-frame-pointer would break Shark but my testing in darwin10 suggests it still can profile code via the dwarf2.
Shark can't get much out of code without frame pointers - callstacks will be truncated and what is there (below the PC of course) will quite often be garbage. It's always recommended that you turn off fomit-frame-pointers for profiling. It generally only makes a few percent difference in wallclock time, so disabling it's not likely to distort your profiling results excessively.
