[lldb-dev] lldb status at windows

Sat Jan 23 11:59:02 PST 2016

im rebuild lldb as x64 application and reabuild my test application with
x64 llvm.
at first look same.
But when my internet was breaked at some moment application under lldb run
and finish correct.
It is like some magic with my pc.
When i have acces to internet lldb hangs, when i disable my internet - it
is correct finished.
I try examine this behavior and determine finite conditions for hangs.
