Describe the bug
Address space layout randomization (ASLR) randomizes the base address of executables. As such, function addresses are specified in the debug sections as offsets from the base address instead of absolute positions. VDB does not currently support this relative addressing scheme, and will crash when attempting to read the relative addresses as absolute.

To Reproduce

1. Import an executable compiled with the -pie flag.
2. Set a break point at any point in the source.
3. Run the target executable.

Expected behavior
The debugger should halt the target process at the break point specified. This should be reflected visually by the UI.

System specifications (please complete the following information):

• OS: Ubuntu 18.04
• Target executable compiler: GCC 7.3.0

Additional context
This problem can be mitigated by compiling executables without the -pie option. However, recent versions of GCC on Ubuntu are built with the --enable-default-pie option. This means that VDB will only function correctly if executables are compiled with the -no-pie option for these versions of GCC.
