Log Message:
PR/10266: t_getstr() leaks memory. This PR will stay in feedback
until the problem gets addressed properly. The following fix
is a stopgap measure to stop the leaking :-(

I fixed the t_getstr() memory leak problem, but that instantly
revealed a problem in t_agetstr() which is an extremely broken
interface. It realloc's memory, potentially moving the area where
it returned pointers into in previous calls. This function needs
to be removed and or changed. I added a horrible work-around for
now, but I will revisit the problem shortly. In the meantime nobody
should be using the t_agetstr() API, and I'll be fixing the rest
of the programs and or the API when I figure out the best solution...
This is t_agetstr() is used by:
