Hi Paul,
I use Eclipse Juno for some projects (Android, Python, LLVM) and the debug works as well as when using native gdb (which Eclipse uses), so anything weird is GDB's fault. ;)

There should be none. O0 is also known as "debug illusion", which is the same as "keep the line information in code sequential order at all costs". Sometimes you get some jumping in C++ (C-tors, D-tors, static objects), but when going through a function, it shouldn't jump too much.

**b) **Are other people using Eclipse (Juno) and are they seeing the same issue? Are there any known ways to fix this chaotic debugger behavior?
I never used ST-Link, so I can't guess about its interaction with Eclipse, but if you have plain old C code compiled at O0, you should have no problems at all, especially with an MS, that is very deterministic.
Have you tried DS-5? Since it's an Eclipse based product and was built specifically for embedded debugging, at least you might want to try it out, using the same toolchain you use today, at least to remove some of the uncertainties...
