fgen free alias in error path

[Loganaden Velvindron]

Hi All,

>From NetBSD:
Coverity CID 1748: Free alias on error.


                        alias->name = strdup(token->text);
                        if (alias->name == NULL)
                                (void)err(1, "out of memory");
                        
                        token = yylex();
                        if (token == NULL) {
                                free(alias);
                                (void)printf( "EOF in alias definition\n");
                                return;

alias->name calls strdup, but it doesn't free it on if (token == NULL).

Shouldn't it be free'ed as well ?
