This patch fixes a crash that is happening because of a null pointer dereference in SBFrame. StackFrame::GetRegisterContext says explicitly that you might not get a valid RegisterContext back but the pointer wasn't tested before, resulting in crashes. This should solve the issue. rdar://54462095 Differential Revision: https://reviews.llvm.org/D83343 Signed-off-by: Med Ismail Bennani <medismail.bennani@gmail.com>
