    I used to use the dbx debugger on AIX, and it had a really nice feature that I wish gdb had. There was a ‘call’ command that allowed you to call any function in the app from a breakpoint. I would add functions to my libraries specifically to allow printing out complex data in variables during debugging – and then use another nice dbx feature, macros, to define simple shortcuts to make it all easy. For example, the system in question used a weird binary date format, but the date library had a DisplayFormattedDate(mydate) function, and I set up a dd(x) alias to it to make this even easier. And of course there was more complex binary stuff similarly displayable. Of course, a nice graphical IDE that wrapped dbx might’ve been even nicer, but this call thing was really powerful. It’d be nice if gdb had something similar – and if IDE’s based on gdb gave you a way to access it (I think kdebug has a command window where you could do that).
