"gdb could not unwind past this frame"

While debugging, I've experienced an intermitent error, "gdb could not unwind past this frame".

I isolated this error occurance to a call to a C function which was the 2nd call to this particular function within a specific Obj-C method.  The C function in question returns an integer however these calls did not specify a return variable --
    i.e., simply "aFunc( … )" vice "nn=aFunc( … )" --
and changing the code to "nn=aFunc( … )" seems to have cured the problem.

I have two questions:
 i) Is failure to provde a return variable a likely cause of the "gdb could not unwind …" error (or was I just lucky this time), and
 ii) Is there any decent discussion of this error and its possible causes? (I sure couldn't find any)?
