There are 2 messages in Mac OS 10.1 where Mac OS 10.2 crashes with bus error.
        tcpBufferedSocket close with READ_DONE Error: 
Invalid_argument("out-of-bound array or string access") READ_DONE Error: 
Invalid_argument("out-of-bound array or string access")
        tcpBufferedSocket close with  useless client
Both are coming from Method close in File tcpBufferedSocket.ml

I can reproduce the first message with connecting via telnet to the core and 
than quit the telnet client.
The 2nd message apears once in a while from 1min to several hours

I found the methods where the calls are generated.
One is generated from shutdown in tcpBufferedSocket.ml and one from 
find_client_zone in donkeyOneFile.ml

I think the problem is that there is a call to close with a non existing socket 
because of the error:
close with READ_DONE Error: Invalid_argument("out-of-bound array or string 
access") READ_DONE Error: Invalid_argument("out-of-bound array or string 
access")
Is this recursive? And if, how do u determine that there is no more socket to 
close?

I compiled the newest version of ocaml 3.06
I compiled the 1.99 mldonkey from CVS (only the mldonkey part)
I did it with on OS X 10.1.5 with the 10.1.5 Developer Tools because i don't 
have the 10.2 DevTools
I tried mldonkey on 10.1.5 and 10.2.1

no bus error in over 12 hours!

#1173 only happens if you are downloading a file with a different size as 
expected. All users would not suffer from it !

For the account, e-mail me directly at address@hidden Yes, I'm interested.

OK, I really need more info and an access to a Jaguar computer. Good info would 
be the fastest configuration of mldonkey, ie the one that crashes after the 
shortest time :) If you have done strange things before, tell me also (for 
example, ran out of space during a download, so that some files might be 
shortened)...

I notice that none of the bugs are assigned to anyone...  Is anyone still 
working on this project?  I wish I could code, I'd fix this damned bug 
myself...  It's most irritating.

one need ocaml 3.06 for the 1.16 mldonkey. it compiles without problems on 
Jaguar 10.2 (actually 10.2.1 6D42) but the bus error still occurs

Please tell me someone is working on this problem...  mldonkey has become 
virtually useless as of the upgrade to Mac OS X 10.2...  This should be a huge 
bug priority...  Is there any information you folks require to get to work on 
remedying this?

Recompiling under Jaguar reduces frequency of "Bus Error" bug, but it still 
exists and can be experienced reliably anywhere from a few minutes to several 
hours after application is launched.

CVS head compiles "out of the box" on Shaguar preview (10.2),
but still reliably dumps core from 1.5 to 15 minutes after mldonkey
starts, with the same problem as noted earlier in this bug.

Also, "quit" at a telnet connection to mldonkey (port 4000),
or quitting the GUI, causes an immediate bus error, unfortunately
without a useful traceback or core dump.

Would a ktrace help?  Preview version allows that, but the output tends
to be B-I-G.

possibly useful informatin from crash reports 
(~/Library/Logs/mldonkey.crash.log) for three SIGBUS deaths where partial state
was available:

The CVS (trunk, 2002 08 17) mldonkey 1.99 gives a bus error 
immediately after the following sequence (with verbose=true)

[FOUND FILE][FOUND FILE][FOUND FILE][FOUND FILE][FOUND 
FILE][QUEUED][FREE][NEXT]Bus error

which of course points to donkey/donkeyOneFile.ml as location of
the culprit code...   This is reliably and trivially repeatable.

I'm trying to recompile with Jaguar Developer Tools (We got Jaguar in at the 
store I work at yesterday) but I keep getting an error message that I don't 
know what to do about:  
crosis% make
cd ocamlopt-3.05; make
make[1]: *** No rule to make target `asmcomp//arch.ml', needed by 
`asmcomp/arch.ml'.  Stop.
make: *** [ocamlopt-3.05/ocamlopt] Error 2
crosis%

Course I'm not exactly a developer... :^)

Is this bug being worked on or does mldonkey just need a recompile with 10.2 
Jaguar Developer tools?
