Hello,
In porting awk to plan9port, maketab.c failed with "Segmentation fault".
Isn’t it better to fix the code as follows:
{
struct xx *p;
- int i, tok;
+ int i, n, tok;
Biobuf *fp;
char *buf, *toks[3];
@@ -133,8 +133,8 @@
i = 0;
while ((buf = Brdline(fp, '\n')) != nil) {
buf[Blinelen(fp)-1] = '\0';
- tokenize(buf, toks, 3);
- if (toks[0] == nil || strcmp("#define", toks[0]) != 0) /* not a valid #define */
+ n = tokenize(buf, toks, 3);
+ if (n == 0 || strcmp("#define", toks[0]) != 0) /* not a valid #define */
continue;
tok = strtol(toks[2], nil, 10);
if (tok < FIRSTTOKEN || tok > LASTTOKEN) {
