As well DDD the X11 front-end for GDB [1]. Helped me quite a lot around 2003.

I still miss a good debugging GUI with useful data visualizations. Sometimes staring at pointers and (multidimensional) arrays of numbers just isn't enough.

For data visualizations I use gdb's Python API. For simple things that can be just adding pretty printers, for hairy things it can be a custom command that prints extra information or dumps it to a graphviz script.

Why do you miss that, I used ddd yesterday.

+1 it kept my sanity regarding lack of good graphical debuggers on *NIX land.

From what I remember when trying to use it, it looked nice but it was very buggy

Not sure it even supported threads for a while

[nineteen999]

Was it DDD that didn't support threads, or GDB though? I remember that GDB support for threads was horrific for a long time, especially back in the 90's.

I have not been tempted by ddd since I found cgdb.
