<pre>When compiling lambda functions, the generated function
names use different conventions than GCC.
Example: <a href="https://godbolt.org/z/5qvqKqEe6">https://godbolt.org/z/5qvqKqEe6</a>
The lambda in Clang is named "_Z3barIZ3foovE3$_0EvT_", while the one
in GCC is named "_Z3barIZ3foovEUlvE_EvT_". Their demangled names are
also different ("void bar<foo()::$_0>(foo()::$_0)" vs "void
bar<foo()::{lambda()#1}>(foo()::{lambda()#1})").
