FACT(s) (Environment):
IBM AIX 6.1
OpenEdge 10.2B 64-bit
OpenEdge 10.2B03
OpenEdge Category: Language (4GL/ABL)
CAUSE:
Bug# OE00205537
CAUSE:
The ending row number of an editor is not updated in sync with the beginning row number when the SCROLL statement is executed, eventually leading to a situation where the row count for the editor is negative. This causes memory to be allocated and cleared improperly, leading to the crash.
FIX:
None at this time.
