Hello Guru's.
I have the following code, and it is core dumping, and i do not know
why :(
{utils.c}
void append_to_file (char *line, char *filename) {
...
fprintf (file, line); // ***** CRASH HERE
fclose (file);
return;
...
gdb reports the following info...
line=0x8213d00 "[Orc] OOC: %n %n\n", filename=0x81353af "../log/ooc"
-or-
line=0x81c5bd0 "[Riseth] OOC: nope i'm 100% new and 95% naive...\n",
filename=0x80fda2d "../log/ooc"
after extensive testing, i've found the code crashes when the following
string is INCLUDED in the variable 'line' => %n %n
**** Any other strings seem to work FINE. ****
it's really weird ... i just don't get it:( everything else is
fprintf'ing to file ....
also, i think this is STOCK CODE from around bp11 or 13, but when i
checked bp21 i couldn't grep it.
Thank you in advance for any help forthcoming :)

append_to_file.\r\n", filename);
mudlog (buf, BRF, LVL_GRGOD, TRUE);
