I can repro this crash in VFP8SP1 but not in VFP9. Looks like it has been fixed. To workaround it in VFP8 you can use LPARAMETERS statement instead of PARAMETERS.


>I found a FoxPro limitation related to Parameters statements when subclassing classes in visual class libraries (VCX). I had a parent class that has procedure with around 20 parameters in it. The total length of the Parameters statement was over 160 characters long. When I subclassed it can tried to modify that procedure and save it, I got this error repeatedly:

>Buffer overrun detected!
>Program...vfp8.exe
>A buffer overrun has been detected which has corrupted the program's internal state. The program cannot continue execution and must now be terminated.
