[lldb-dev] LLDB-MI remote debugging on Linux

[Pavel Labath via lldb-dev]

Hi,

this is a known problem and somewhat embarrassing problem, but
unfortunately we haven't had time to look at that yet. The code that is
doing that was added to support loading of the vdso, which is only present
in the application memory (and it is a full elf file). I don't think
anybody has realized the full implications of this when it was being added.
Patches fixing this would be very wellcome.
