I sure hope someone appreciates that offer enough to help. I think I'm out of my mind. There are 68 of them in the source tree now and they have tendrils all over the place. But I did my share of shouting about how much of GDB was deprecated and then left to rot; I do not want to contribute to the problem. I'm not volunteering to test all of them, but I'll test the ones I can and make mechanical fixes to the rest. Fortunately about half of those use trad-frame.c. -- Daniel Jacobowitz CodeSourcery
