Bug ID: 18212
Summary: async nature of lldb startup with a core file could be
confusing to user
Product: lldb
Version: unspecified
Hardware: PC
OS: FreeBSD
Status: NEW
Severity: normal
Priority: P
Component: All Bugs

Classification: Unclassified
I opened a (large) clang core in lldb, and could enter commands at the (lldb)
prompt before the initial stop notification, resulting in an "invalid thread"
message that could be confusing to new users.
Core file '/tmp/clang-3.4.core' (x86_64) was loaded.
(lldb) bt
error: invalid thread
