Hi,
I've been installing 4.0-current and testing it. One of the
problems I've found is with the port elm2.4.ME+.68 ...
/usr/ports/mail/elm/work/elm2.4.ME+.68/lib/can_open.c function
'can_open()' checks for the presence of the mail folder (which
doesn't exist). It returns an appropriate error.
Unfortunately, we seem to loose the bad rc.
/usr/ports/mail/elm/work/elm2.4.ME+.68/lib/mail_gets.c function
'mail_gets()' is called later with a NULL filepointer which is
then passed to feof() and ferror().
Starting "./bin/elm "
elm:\elm.c\main 42
> g
SIGSEGV - Segmentation violation.
elm:\mail_gets.c\mail_gets 31 (+0x6)
int mail_gets(buffer, size, mailfile)
char *buffer;
int size;
FILE *mailfile;
{
register int line_bytes = 0, ch;
register char *c = buffer;
size--; /* allow room for zero terminator on end, just in case */
31->>> while (!feof(mailfile) && !ferror(mailfile) && line_bytes < size) {
ch = getc(mailfile); /* Macro, faster than fgetc() ! */
Note, the above all works correctly if you actually have a valid
mail folder.
The following patch fixes the problem, though I don't beleive
it is truely the correct fix.
