[Lldb-commits] [PATCH] Fix -gdb-exit to detach if was attached or destroy otherwise (MI)

Thu Mar 26 00:49:09 PDT 2015

Hello @clayborg,

I added the switch() back in Process::Finalize() in r233258, because it caused an error:

  $ bin/lldb
  (lldb) target create ~/p/hello
  Current executable set to '~/p/hello' (x86_64).

  Assertion failed: (!"bad_weak_ptr"), function shared_ptr, file /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/memory, line 5174.
  Abort trap: 6

backtrace:
