Segfault when input is incorrect

[federicoemartinez]

I have tried to encode this file:

Main {
DsPacketClass
{
ClassifierRef 1;
ServiceFlowRef 1;
RulePriority 0;
ActivationState 1;
IpPacketClassifier {
IpSrcAddr 127.0.0.1;
}
LLCPacketClassifier {
EtherType 00257;
}
}
}

I would expect it to fail with an error, but I get segfault. I think the problem comes for the fact that the parsers put a number in yylval->intval and then the function to process an hexstring is called, which expects the value in yylval->strval;
