Workaround segfault in clang's mangling code that is tickled when
attempting to mangle the declaration:
std:__ndk1::__find_detail::__find_exactly_one_checked::__matches
in the <tuple> header in the Android NDK.
This codepath is exercised by MozsearchIndexer.cpp (the searchfox
indexer) when indexing on Android. See also
