Full Text Bug Listing

While batch processing a huge junk file, I had numerous cores in bogofilter
that looked like this:

#0  0x0000000000413b7f in parse_new_token (token=0x7fff424891c0) at token.c:355
355                     if (text[leng-1] == '>') {
(gdb) bt
#0  0x0000000000413b7f in parse_new_token (token=0x7fff424891c0) at token.c:355

(gdb) p leng
$1 = 0
(gdb) p token->leng
$2 = 4
(gdb) p text[-4]
$4 = 32 ' '
(gdb) p text[-3]
$5 = 105 'i'
(gdb) p text[-2]
$6 = 100 'd'
(gdb) p text[-1]
$7 = 32 ' '


Naive fix attached, which worked for me to remove all the cores.

lexer change to fix QUEUE_ID problem

Torsten,

I've reproduced the problem by splitting "id <identification>" across two
lines.  The parser expects a single space in the middle of the QUEUE_ID. My fix
is to allow spaces and newlines.

David

Thank you, David.

Daniel, can you please test it with your huge junk file?

Didn't fix it entirely, I still get the same core, but only 4 instead of 12, so
it helped.  Maybe I can knock up a script to figure out which mails cause the
core.

Emails that cause bogofiler to crash

Okay, here's the set of emails that cause bogofilter to crash even with the
lexer change.  I've also sent this to the upstream maintainer in response to
the email thread.

This appears to be related to being on amd64.

Replacement patch

I had to change the definition of ID as well.  With this patch, I get output
from all those emails.
