Thanks Peter and Tom. I haven't actually checked that a segmentation fault
lists my function in the stack trace properly (I fixed that fault by code
inspection) however, I had discovered that once the function had run without
faulting the symbols were there. There's too many variables to check properly
now but I had tried using LOAD before and it made no difference but then I
might not have tried the LOAD then attach gdb sequence.
The principal mistake I think was my forgetting that the load isn't done until
the function is first used.
