Hi.
Im trying to use GDB within proot with the 4.0.3 release. It seems to work fine on x86-64 with most programs. Some do "hang" however and never break. Heavy multithreaded applications suffer most problem with a total hang without ever reaching a bp. So far I don't have a grasp on what the problem seems to be. I can see that PTRACE_PEEKSIGINFO and PTRACE_SETOPTION are missing. Delivering signals in multithreaded applications is a bit of a nuisance, but why would proot break that? Shouldn't all signals be delivered by default after stopping?
