[PATCH] D80371: [clang-tidy] Fix potential assert in use-noexcept check

[Nathan James via Phabricator via cfe-commits]

njames93 added a comment.

Figured out the actual cause of this bug, `getExceptionSpecRange()` returns a null range if the function has an unknown return type

  undefined_type throws() throw();

This is the tidy output (where assertions are disabled)

  warning: dynamic exception specification '' is deprecated; consider using 'noexcept' instead [modernize-use-noexcept]
