Howdy, just finished generating code for my first try at antlr, and it
crashes during parsing (pardon me if this is a known issue, still finding my
way around the website/wiki)
It's erroring during parsing, and crashing while printing the error message,
Looks like I still have work to do on my grammar =)
antlr3commontoken.c line 346
token->tokText.text = token->strFactory->newStr8(token->strFactory,
(pANTLR3_UINT8)"<EOF>");
the strFactory pointer is not valid in my case. I have not yet found where
strFactory is assigned to. I can get around this by setting up the factory
manually:
pANTLR3_INPUT_STREAM input = ...
pFactoringLexer lexer = ...
pANTLR3_STRING_FACTORY stringFactory = antlr3StringFactoryNew();
lexer->pLexer->rec->state->tokSource->eofToken.strFactory = stringFactory;
pANTLR3_COMMON_TOKEN_STREAM lexTokens =
antlr3CommonTokenStreamSourceNew(...);
pFactoringParser parser = ...
parser->progStart(parser); // crash here
