Sequence Editor of Test Executive Causes a General Protection Fault if Numeric Limits Exceed a Certain Number of Digits

Primary Software: LabWindows/CVI Add-ons>>Test Executive
Primary Software Version: 1.0
Primary Software Fixed Version: N/A
Secondary Software:

Problem: Why does CVI cause a General Protection Fault (GPF) if the limits in the sequence editor are in the millions (e.g. GT 12,999,999.0 and LT 13,000,001.0)?

Solution: This crash occurs within txedseq.c in the GenerateCompareTypeString() function (on line 2116), which is called from several places. The function calls that cause problems are in the LimitCallBack(), EditTest() and UpdateSeqListing() functions.

In these functions, the definitions of OutputString and iString need to be increased in size to accommodate larger numbers.
