[antlr-interest] C runtime Memory Usage

[Bot Tiger]

Hello, I am using the C runtime and experiencing heavy memory usage.

I am interpreting an AST tree recursively.

In each interpret call, I am checking the token text by using
pANTLR3_BASE_TREE->getText()->chars.
Am I suppose to manually free this when I am done with it?

Also, I am recursively calling the children nodes with
pANTLR3_BASE_TREE->getChild().
Am I also supposed to free these as well? I was assuming that they returned
only 1 copy of the node.

Thank you.
