Just found this debugger...

[solidstate1991]

I wanted to do some work on lzbacon (D port of lzham-codec with 
some extras such as tarball support), but without a debugger it's 
pretty hard (I suspect an error in the multithreading when 
looking up for a value, or some C++ language quirk I missed). The 
current state of mago-mi is nearly unusable with very limited 
command support, and I don't want to go back to VisualD after 
VSCode for either a usable mago or VS native debug. I couldn't 
find LLDB on my harddrive anymore, and GDB needs DWARF symbols.

Then I had a thought: Is there anything usable on the market 
besides these?

After I a quick Google search, I encountered with the "guy she 
told you to not to worry about":

It seems it needs *.pdb files for symbols, which I'll test 
tomorrow, hopefully I don't have to cook something complicated 
for my family to waste my time. While I'm still encouraged to 
improve mago instead (I think alternatives are always a good 
option and the conversion will be finished by the weekend), maybe 
it'll be useful for some. Maybe I can use it for mago too.
