Thank you Martin
I normally use objdump for DWARF info but, I was curious about what was available in Lazarus and figured I'd try the test programs that are part of it, among them fpdumpdwarf.
I also had a look at dwarfviewer with mixed results. Clicking on the "show lines" button usually works fine but, clicking on the button that is above it (I think labeled 'show info" or something like that) causes the program to consume hundreds of megabytes of memory until it causes an exception (apparently due to stack exhaustion.)
Nothing critical though, as you pointed out, objdump dumps DWARF info just about any way a programmer would want to look at it. That said, it would be nice if, time allowing, those test programs/utilities could be made to work again. (if I were more adept at OOP, I'd gladly contribute but, I'm more likely to cause more harm than good.)
Again, thank you for the help.
