[antlr-interest] antlr3.4 C target Bug ?

[Rampon Jerome]

Hi,

For info ...


Something like a bug apparently (with C output and antlr3.4 version)

On missing EOF

in recoverFromMistmatchedToken, ... getMissingSymbol
from code testing EOF  (pANTLR3_COMMON_TOKEN) MATCHT(EOF, &FOLLOW_EOF_in_...);

around line 2219, following code

text->append8(text, (const char *)recognizer->state->tokenNames[expectedTokenType]);

expectedTokenType has no real entry in tokenNames array

Returns NULL, then crash

Maybe already reported. I made a local fix in my version in append8

with expectedTokenType == EOF ? ....


Regards


Jerome
