This may turn out to be a gdb bug.

- I start a gdb session with breakpoints.
- I hit a break point and there are no problems.
- I add some watch variables, and eventually, when I step I get messages from gdb (via a pop up) that looks like:

Type <data variable, no debug info> is not a structure or union type.

In the debugger console this corresponds to the following:

(gdb) 
653-var-evaluate-expression var72
652^error,msg="Type <data variable, no debug info> is not a structure or union type."

This remains even if I remove all the watch variables.

What version of gdb do you use?

This is really a gdb bug. I'll file it and provide a link here.

Thanks. I have seen this off and on for years. Do you think any of the newer versions of gdb have this fixed? And although this is a gdb bug, is it possible that NB does something specific (perhaps stimulated by structures in my code) that tickles the gdb bug?

I don't think so.
