            Bug ID: 24302
           Summary: Module functions not available for the first call
                    after module import
           Product: clang
           Version: trunk
          Hardware: Macintosh
                OS: MacOS X
            Status: NEW
          Severity: normal

After import a module from lldb, the functions in this module aren't available
in the first call, subsequent calls to the same function are ok.

It could be reproduced by these steps, 

Launch TOT lldb on MacOSX,
(lldb) expr @import Darwin
(lldb) expr MIN(5, 8)
error: use of undeclared identifier 'MIN'
error: 1 errors parsing expression
(lldb) expr MIN(5, 8)
(int) $0 = 5
(lldb) expr MIN(5, 8)
(int) $1 = 5

This started to happen after
