Hi
MY code kept on giving segfaults..
So I traced it..
in antlr3commontree.c:
function newPool: ( around line 99)
basicly the ANTLR3_CALLOC there to create a new pool fails after a while..
Runs out of memory :(
But If you print out factory->thisPool then it runs very high.. high
enough to flood a GB or 2..
anyways this causes segfault in newPoolTree.
segfault happens usually on this line:
tree->baseTree.super = tree;
Not sure how to fix but I'm suprised the thing runs out of memory :(
I'm guessing it has todo with the way backtrace or memoize is implemented?
Attached is the .g grammer file..
And also the testme.txt file on which this things segfaults itself.
btw. using cygwin
thanks for any help..
