Maybe, but no reason jumps >out at me. Er, infrun single-steps through trampolines rather than skipping over them. Oh right. This would leave us sitting in the trampoline instead of automatically skipping them; makes sense. (note the choice of word - trampoline - there are many types of trampoline and for each GDB either steps through it or returns from it) Another [SIGTRAMP_FRAME] attribute is how to display it when doing a backtrace or stop.
