The original source, clang++ output, preprocessed source and run script
I was writing a class registry macro, and accidentally picked the same name for
my lambda argument as the registered class. With g++, this gives a compiler
error, but for clang++ (since at least 6.0), it segfaults.
I have split the statements into three groups. Each one acts as described in
isolation, or as part of a whole.
I rather confident that this isn't exploitable. This appears to be a null
pointer dereference rather than anything more scary, and after half an hour of
poking around, I couldn't get anything out of it. So I get that this is not a
*huge* priority, as the code itself is not well-formed, but clang probably
shouldn't explode like this.</pre>
