Hi Pavel,
thanks for your quick reply.
I filed a bug at https://llvm.org/bugs/show_bug.cgi?id=24958.
I'll try to determine a more precise revision range for that issue. I am
currently using svn (checking out lldb manually into llvm/tools).
Do you have a recommended workflow for git in such a situation? git
bisect with subtree / submodule?
Cheers,
Stefan

Hi,
Thanks for the report. Since you are suspecting a deadlock, could you
post a backtrace of all the threads (thread apply all backtrace). It
would be best to move this discussion to a bug in llvm.org/bugs.
I am currently using svn revision 247535 of llvm and lldb, and I know that my
code was working with svn revision 229496
This sounds like a pretty big revision range. It would help if you
could narrow it down a bit.

Hi,
I've got a problem with lldb deadlocking upon a call to
lldb::SBDebugger::Terminate().
I am currently using svn revision 247535 of llvm and lldb, and I know that
my code was working with svn revision 229496.
In short, I am doing the following steps:
lldb_debugger = lldb::SBDebugger::Create()
lldb_debugger.SetAsync(true)
lldb_target = lldb_debugger.CreateTarget()
lldb_process = lldb_target.AttachToProcessWithID()
... (doing stuff with modules)
lldb::SBDebugger::Terminate()
The last call results in a deadlock.
I enabled the DEBUG_LOG and ENABLE_MUTEX_ERROR_CHECKING macros within
Mutex.cpp and found out that a mutex is getting locked whose ID never came
up in the log before. This mutex has no owner, so it should be lockable -
but it isn't...
A gdb backtrace with the last few debug messages can be found here:

Does anyone have an idea what is going on here? Am I missing something?
Thanks in advance!
Cheers,
Stefan Kratochwil
