YY_FATAL_ERROR only prints a message instead of halting execution — in the configuration file parser's lexer. Tension: allowing flex-generated code to continue past safety checks. Outcome: when yyleng >= YYLMAX, the subsequent yy_flex_strncpy call overflows the yytext buffer because YY_FATAL_ERROR returned instead of exiting.
