I have made a discovery, although I am not sure if it is absolutely
consistent with the behavior I am observing. Observing the profile in
Shark's tree view, such that I can view the call stack from 'start'
all the way down, it appears as if Shark finds source code all the way
down a call stack until a function pointer call, i.e., a stack frame
allocated not from a typical static function call, but from a function
pointer determined, obviously, at runtime. The next level after the
function pointer, and all other levels all the way down, suffer the
problem I have described -- Shark shows no source for those frames.
Any thoughts on this?
