[lldb-dev] SystemInitializerCommon::Initialize called twice with shared llvm build

[İsmail Dönmez]

And setting a break point on
lldb_private::SystemInitializerCommon::Initialize() shows that 2
initializations indeed:

First one:

#0  lldb_private::SystemInitializerCommon::Initialize (this=0x1ccec10)
at ../tools/lldb/source/Initialization/SystemInitializerCommon.cpp:96
#1  0x00007f76d64385cd in
lldb_private::SystemInitializerFull::Initialize (this=0x1ccec10) at
../tools/lldb/source/API/SystemInitializerFull.cpp:226
#2  0x00007f76d6612a3a in
lldb_private::SystemLifetimeManager::Initialize (this=<optimized out>,
initializer=..., plugin_callback=0x7f76d63ffbf0
<LoadPlugin(std::__1::shared_ptr<lldb_private::Debugger> const&,
lldb_private::FileSpec const&, lldb_private::Error&)>) at
../tools/lldb/source/Initialization/SystemLifetimeManager.cpp:43
#3  0x00007f76d63ffbc7 in lldb::SBDebugger::Initialize () at
../tools/lldb/source/API/SBDebugger.cpp:123
#4  0x00000000004063bb in main (argc=1, argv=0x7ffc50c8c948,
envp=0x7f76d6438f80 <LLDBSwigPythonWatchpointCallbackFunction(char
const*, char const*, lldb::StackFrameSP const&, lldb::WatchpointSP
const&)>) at ../tools/lldb/tools/driver/Driver.cpp:1223

Second one (this happens after I do "file ls" and "r") :

#0  lldb_private::SystemInitializerCommon::Initialize (this=0x1096850)
at ../tools/lldb/source/Initialization/SystemInitializerCommon.cpp:96
#1  0x00007f11ba252a3a in
lldb_private::SystemLifetimeManager::Initialize (this=<optimized out>,
initializer=..., plugin_callback=0x0) at
../tools/lldb/source/Initialization/SystemLifetimeManager.cpp:43
#2  0x00000000004160fe in initialize () at
../tools/lldb/tools/lldb-server/lldb-server.cpp:38
#3  0x0000000000415fde in main (argc=6, argv=0x7ffc6179b168) at
../tools/lldb/tools/lldb-server/lldb-server.cpp:62
