GCC 11.2.0 -fanalyzer reports the following error in a generated parser:


error: ‘free’ of ‘yyss1’ which points to memory not on the heap
[CWE-590] [-Werror=analyzer-free-of-non-heap]


referring to the following part:


#  undef YYSTACK_RELOCATE
        if (yyss1 != yyssa)
          YYSTACK_FREE (yyss1);
      }
# endif


Since this does not seem specific to my parser, I'm posting here.

This may be a false positive from the static analyzer, though.
