The code contains the fix. It's the safefree() in line 4985. The
previous version called free(). I changed this because the
ARControlStruct object is allocated with safemalloc() in line 233
(function ars_Login). Before the fix I had the same problem (segfault
on script termination, i.e. even after a successful call to ars_Logoff)
on Windows XP.
You mentioned in another mail that the problem occurs if the script
calls only ars_Login() and ars_Logoff(). Does the segfault also happen
if you omit the ars_Logoff() ?
