Hi.
This is a bug I've found in amuled that is yet not solved (at least for amule-cvs-20071112). It happens when launching amuled and it starts kademlia. I've debugged amuled with gdb and found the problem in SafeFile.cpp, CFileDataIO::ReadTag, line 456:
} catch (...) {
printf("Invalid Kad tag; type=0x%02x name=0x%02x\n",
type, ((const char *)unicode2char(name))[0]);
delete retVal;
throw;
}
The problem is that sometimes unicode2char returns NULL, and so trying to access character at pos.
- triggers an exception. I patched it as follows:
} catch (...) {
// Do not try to print first byte of name, unicode2char sometimes returns NULL
printf("Invalid Kad tag; type=0x%02x\n", type);
printf("Invalid Kad tag; name=%s\n", ((const char *)unicode2char(name)));
delete retVal;
throw;
}
This is the backtrace of the error:
