"""
Tests that the expression evaluator is able to deal with types
whose definitions conflict across multiple LLDB modules (in this
case the definition for 'class Service' in the main executable
has an additional field compared to the definition found in the
dylib). This causes the ASTImporter to detect a name conflict
while importing 'Service'. With LLDB's liberal ODRHandlingType
the ASTImporter happily creates a conflicting AST node for
'Service' in the scratch ASTContext, leading to a crash down
the line.
