These NetHacks( nethack, nethack-qt and japanese/nethack)
has Y2K problem
Look at function yymmdd() which is in 'hacklib.c'. This function
generate 'datestr' with 6 degits format, But 'datestr' has only 7
bytes so the NetHack cannot write 7 degits.
yymmdd()
{
...
Static char datestr[7];
...
...
Sprintf(datestr, "%02d%02d%02d",
lt->tm_year, lt->tm_mon + 1, lt->tm_mday);
...
...
}
Above function is used at generating log and record. Unfortunately
when reading, the NetHack uses fscanf as bellow(see src/topten.c)
static char *fmt = "%d %d %d %ld %d %d %d %d %d %d %6s %6s %d%*c%c%c %s %s%*c";
~~~ ~~~(created by yymmdd)
So, NetHack cannot read 7 degits record file and cause dumping core.
The easy way to fix this problem, fix yymmdd() in src/hacklib.c as bellow.
Sprintf(datestr, "%02d%02d%02d",
lt->tm_year % 100, lt->tm_mon + 1, lt->tm_mday);
It seems 'yymmdd' function has no effect for playing game. It used
only writing log and record. So I think above fixing will work
correctly.(and easy)
