| Thanks I had them both in Dystopia.h ....
This seems to be the culprit.
/*
* Read one word (into static buffer).
*/
char *fread_word(FILE * fp)
{
static char word[MAX_INPUT_LENGTH];
char buf[100];
char *pword;
char cEnd;
do
{
cEnd = getc(fp);
}
while (isspace(cEnd));
if (cEnd == '\'' || cEnd == '"')
{
pword = word;
}
else
{
word[0] = cEnd;
pword = word + 1;
cEnd = ' ';
}
for (; pword < word + MAX_INPUT_LENGTH; pword++)
{
*pword = getc(fp);
if (cEnd == ' ' ? isspace(*pword) : *pword == cEnd)
{
if (cEnd == ' ')
ungetc(*pword, fp);
*pword = '\0';
return word;
}
}
word[20] = '\0';
sprintf(buf, "Fread_word: word '%s' too long.", word);
bug(buf, 0);
my_exit(1);
return NULL;
}
Also it makes reference to
void boot_db(bool fCopyOver)
load_artifact_table();
and
void load_artifact_table()
{
FILE *fp;
char *word;
log_string("Loading Artifacts");
if ((fp = fopen("../txt/artifacts.txt", "r")) == NULL)
{
bug("Unable to open artifacts.txt", 0);
abort();
}
word = fread_word(fp);
while (str_cmp(word, END_MARKER))
{
struct arti_type *artifact = malloc(sizeof(struct arti_type));
artifact->owner = str_dup(word);
artifact->vnum = fread_number(fp);
artifact->active = fread_number(fp);
artifact->fun = fread_string(fp);
AttachToList(artifact, artifact_table);
word = fread_word(fp);
}
fclose(fp);
}

| | Look in /txt/artifacts.txt for anything corrupt. |

| | If you're sure load_artifact_table is causing this, set a breakpoint at it and then step into fread_word and print out any info there. |

| Another approach to capture if the MUD exits by calling exit(1) is to put a breakpoint on exit, like this example program:
#include <stdlib.h>
void a (void)
{
exit (1);
}
void b (void)
{
a ();
}
int main (void)
{
b ();
return 0;
}
Now if I run gdb, I want to find where in the code exit is called:
$ gdb test
GNU gdb 6.8-debian
(gdb) break exit
Function "exit" not defined.
Make breakpoint pending on future shared library load? (y or [n]) y
Breakpoint 1 (exit) pending.
(gdb) run
Starting program: /home/nick/development/test
Breakpoint 1, 0xb7ea8d06 in exit () from /lib/tls/i686/cmov/libc.so.6
(gdb) bt
#0 0xb7ea8d06 in exit () from /lib/tls/i686/cmov/libc.so.6
#1 0x080483d6 in a ()
#2 0x080483e1 in b ()
#3 0x080483f9 in main ()
(gdb)
Note the warning message about exit not existing just yet, but it picked it up after the libraries were loaded. Then when exit was called, you can see it was indeed located in function "a" called by function "b" called by "main". |
