stack-based buffer overrun.

[Unknown]

Hello Juan,

I have run a build and installed fuzzylite

however when I try to run an example, Visual Studio crashes with the exception:

“Unhandled exception at 0x010346F9 in fuzzytesting.exe: Stack cookie instrumentation code detected a stack-based buffer overrun.”

This seems to happen with the execution of:

ruleBlock->addRule(fl::Rule::parse(“if AllInputTerms is A then AllOutputTerms is T”, engine));

Any help would be greatly appreciated!

Kind Regards,
Ramy

Hi,

thanks for your post.

could you please post the entire code to test in my computer?

Cheers.

Hello Juan,

it is one of the examples of fuzzylite:

#include <fl/Headers.h>

int main(int argc, char** argv){
using namespace fl;

Hi,

your error is very odd as I successfully ran the tests on fuzzylite in Windows using that example. Are you using the library correctly? Could you be linking to an old version of the library? Are you using the latest version 5.0? How are you including the library in your project?

I managed to run the example perfectly in Linux using:

g++ AllTerms.cpp -Ifuzzylite-5.0/ -Lfuzzylite-5.0 -lfuzzylite-static -o AllTerms.o
./AllTerms.o

In Windows, please find the equivalent command.

Cheers.
