hi, this is Solaris x86 system, it runs xmule okay, this is first time I compiled amule on it. It starts up, copied .xmule away, started connecting, connected, then after some time, without any action on my side, crashes.

Weird. According to the BT, you don't have event table, you don't have GUI, and you don't have preferences.
Weird, to say the least. I'll research on this bt.

CVS on sf 11.Jan.2004 still has the same issue.
Now amule runs longer, but few minutes after connecting to server, crash.
this time compiled with: ./configure --enable-debug --disable-optimise --enable-safetray
gdb is 6.0, gcc is 3.3.2

I also notice alot of strange disconnected clients, like these:

%F 14:01:33: Client 'aijvrc' (IP:xxxx) caused an error: 2. Disconnecting client!
%F 14:06:34: Client 'seb73' (IP:xxxx) caused an error: 134. Disconnecting client!
errno.h:
#define ENOENT 2 /* No such file or directory */
#define ENOTCONN 134 /* Socket is not connected */

if (theApp.glob_prefs->GetVerbose()) {
if (client) {
theApp.amuledlg->AddLogLine(false,CString(_("Client '%s' (IP:%s) caused an error: %u. Disconnecting client!")),
client->GetUserName(),client->GetFullIP(),nErrorCode);
} else {
theApp.amuledlg->AddLogLine(false, CString(_("A client caused an error or did something bad. Disconnecting client !")));
}
}
Disconnect();
Line 4 above is what triggers crash. I'll try running with verbose off.
So, above it seems that client->GetUserName() returns NULL. I wonder if it would be right to change to:
client->GetUserName() ? client->GetUserName() : ""
or should this be done in client->GetUserName()?

1. uncheck verbose in preferences - tweaks
2. use better berlios anon cvs.. i updated it 2 mins ago and its allready synched.. the tarball -> http://cvs.berlios.de/cgi-bin/viewcvs.cgi/amule/amule-cvs/amule-cvs.tar.gz?tarball=1

Commited the fix to CVS
