clang::ASTContext::getAsArrayType(clang::QualType) const segfaults

I'm getting a segfault by running Clang-Tidy which asks to file a bug report here. Here's the report.

Check out coredumpctl list.

You might want to add some info about the distro and package version, since this doesn't happen everywhere.

Could you please try 16 or main branch? https://godbolt.org should be helpful.

Version 15 is the last one packaged on my system (Ubuntu 22.04) sorry
