[Lldb-commits] [PATCH] fix debugging on linux

[Duncan Sands]

As a side-note, there is a buildbot trying to build and test lldb on linux.  If
you look here
   http://lab.llvm.org:8011/console
you will see this builder
   http://lab.llvm.org:8011/builders/lldb-x86_64-linux
which is compiling lldb, but tests are failing:
      The evaluating printf(...) after break stop and then up a stack frame. ... 
python: Host.cpp:42: static lldb_private::Error 
lldb_private::Host::LaunchProcess(lldb_private::ProcessLaunchInfo&): Assertion 
`!"Not implemented yet!!!"' failed.

Should this buildbot be managed from the general LLVM build master like this,
or does lldb have its own build master?

Ciao, Duncan.
