In ReorderFieldsAction.cpp
The linkage of
<span class="quote">> @_ZN5clang12ast_matchersL10recordDeclE = internal constant %"class.clang::ast_matchers::internal::VariadicDynCastAllOfMatcher.916" undef, align 1</span >
changed to
<span class="quote">> @_ZN5clang12ast_matchersL10recordDeclE = external global %"class.clang::ast_matchers::internal::VariadicDynCastAllOfMatcher.847", align 1</span >
We should figure out what went wrong there.</pre>
