clang-p2996/lldb/source/Plugins/ABI/MacOSX-arm/ABIMacOSX_arm.cpp
Sean Callanan 866e91c9d4 Better error reporting when a variable can't be 
read during materialization.  First of all, report
if we can't read the data for some reason.  Second,
consult the ValueObject's error and report that if
there's some problem.
