View snaps to bottom of file when stepping into a function

[luis-reyes-a]

Hello, in this clip I'm trying to step into a function. When I do, first it focuses on the disassembly instruction. I step over and it takes takes me to the start of the function. When I step over again, the view scrolls all the way to the bottom of the file. Stepping over again, fixes this and takes me back to where I was in the function.

(I don't think it matters but I'm calling the function through a macro (it doesn't do anything special but some token concatenation to call the function)

Hmm. I think this is two bugs in one. The first, the step-into stopping at the jump table, has been fixed in 5fe3f56. The second is probably a new edge case in line info, so I'll put on my list to check that one out.

Hey Ryan, not sure if it helps but the view snapping to the bottom of the file happens EVERY time I step into a function. Looking at videos of other people using the debugger, it seems to not be the case. I suspect maybe it has to do with the way I laid out my debugger windows or something? Here's another recording of this happening in latest build [28e258b]

I don't think it should have anything to do with the panel layout you have. Can you provide more information about how you're building your EXE - what compiler, what version, what flags, what linker, etc.? And, if possible, can you send me a small test EXE/PDB which minimally reproduces the issue on your end?

To build raddebugger, I'm using msvc 19.29.30133 and all I do is go to the root folder and run build.bat.

I suspect it may be because the program I'm trying to debug is using msbuild. I tried to recreate the problem just making a build.bat that calls cl but couldn't make it happen. Making a project in visual studio and calling msbuild did it for me. I think it also only happens when you jump to a function in a different file. Here is an example project. Just step into the function calls I have in main()

Looks like this is because of the /JMC (Just My Code) option, which is presumably turned on by default with the usual msbuild setup. Looking into how the debugger ought to handle this.

This should be resolved in f130f23. Let me know if you run into additional issues with it.
