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.
