        <pre>When I'm trying to evaluate block within lldb session from Xcode:
    expr ((void (^)(id, id))MyCompareBlock)(obj1, obj2)
I get the following error:
    blocks support disabled - compile with -fblocks or pick a deployment target
that supports them

An Apple Employee (Jim Ingham) confirmed that LLDB does not support them yet:
