Thanks for catching my bugs. The reason I didn't free the memory in plbuf_tidy() was to facilitate reuse of the memory. The plbuf_bop routine calls plbuf_tidy() and in my application I call plbuf_bop() frequently. The constant malloc/free calls will kill performance and fragment the heap. In plbuf_bop I set pls->plbuf_top = 0, which has the same effect as discarding the contents of the buffer. My recommendation is to go to the previous version of plbuf_tidy and free the memory via a call in c_plend. I can submit a patch if this is an acceptable solution. cheers -jd ------------------------------------------------------------------------- Take Surveys. Earn Cash.
