Infinite loop when reformatting a macro

[mathstuf]

Configuration: https://gist.github.com/mathstuf/d28e774a3f7b3e7f058db1a65b1cf9f3

Source:

#define CREATE_HAS_CHECK( funcname ) \
  template< typename T > \
  class has_##funcname \
  { \
    enum { value = sizeof(test<T>(nullptr)) == sizeof(r1) }; \
  }

(trimmed down from a more comprehensive example hence the dangling r1 reference)

Command: uncrustify -c .uncrustify.cfg -f infinite-loop.h

-p debug.txt was attempted, but as it doesn't seem to ever complete, the file was never created.

% uncrustify -v
