The bug is not recently introduced.
It has been existing for years because was hidden by someone who disabled
checking for AE_SUCCESS value returned by AdsGet*() functions and hardcoded
the size of returned value to maximum size of declared field ignoring real
size returned by ADS.
Recently it was was only exploited when I added support for varlangth fields
for which is necessary to check the real size and now it's fixed by:
2009-05-14 19:20 UTC+0200 Przemyslaw Czerpak (druzus/at/priv.onet.pl)
* harbour/contrib/rddads/ads1.c
! fixed minimal record buffer size calculation
! fixed adsGetValue() method hacked to not report errors due to too
small field buffer.
Warning! Now ADS RDD will report any error as RTE if sth wrong
will happen in one of AdsGet*() function when field is read so
it's possible that also some other hidden bugs will be exploited
and you will see RTE. Please test it.
Looks that the ChangeLog message was not delivered yet to Harbour
mailing list yet.
best regards,
Przemek
