HI,

I have the following question about bison:--

When the bison generated parser encounters an error in the input
expression and there is no error recovery grammar then the forrest of
linked up structures that may have been created as part of parsing need
to be cleaned up else every wrong input stream causes this memory to be
allocated and not get deleted at all when the parser is working as part
of another thread.

Is there some standard functionality available to do some cleanup
associated with the values associated with bison's internal stack ?? for
instance something that lets you iterate over all the
values in the stack and delete them.

thanks for the help
