llvm-project/lldb/source/API/SBData.cpp
Greg Clayton 5160ce5c72 <rdar://problem/13521159> 
LLDB is crashing when logging is enabled from lldb-perf-clang. This has to do with the global destructor chain as the process and its threads are being torn down.

All logging channels now make one and only one instance that is kept in a global pointer which is never freed. This guarantees that logging can correctly continue as the process tears itself down.
