MAIN QUESTION:
I can't seem to find any reference to my functions in the stack dump.
The range of function addresses in the stack dump is 0x61002F32-0x7C802542
and yet my functions should be somewhere in the 0x00401000-0x004040A5 range
(according to objdump and nm).
Is this due to the "Error while dumping state"?
How can the error be resolved?
MINOR QUESTIONS (feel free to ignore):
This is my first time looking at a stack dump (only some limited
micro-controller assembly experience from many years ago).
Am I correct that the "Function" column represents the logical/virtual
return
address of the next instruction of the function in memory?
Am I correct that the "Frame" column represents the logical/virtual
address of
the function call in the stack?
OFF TOPIC QUESTIONS (feel free to ignore):
How useful could a stack dump be for diagnostic purposes with functions of
dynamically loaded shared libraries (via. dlsym)? Couldn't the function
address be potentially different every time the program was executed?
