(Somehow, I thought it actually did work at some point in the > past, but maybe I was dreaming.) Indeed, I tried it on 5.3 and 6.0 gdbs, and it worked. Looking at the code, I guess it broke with the support for multi-location breakpoints, in 6.8. I guess I shall drop the NEWS entry, as it's a regression fix afterall? I think I'll add a simple test that watches for "watch $pc", so that we don't regress again. That expression should be portable. -- Pedro Alves
