Hi Johan, If it is Apple specific, create a report on the Apple Bug Reporter, at https://bugreport.apple.com/ <https://bugreport.apple.com/>.
If you can reproduce the error with stock lldb, please report it on the LLVM bugtracker, at https://bugs.llvm.org/enter_bug.cgi <https://bugs.llvm.org/enter_bug.cgi>. -Dimitry > On 18 Jan 2018, at 15:08, Johan Øverbye via lldb-dev > <lldb-dev@lists.llvm.org> wrote: > > Hi :) > > I hope this is an appropriate use of this mailing list, my apologies if not. > I couldn't find any form to report LLDB bugs and wasn't sure where to ask. > > With a recent update of Xcode I started getting an LLDB crash frequently > while attempting to debug.
