C++20 compilation leads to segmentation fault in erode and dilate

Question

C++20 compilation leads to segmentation fault in erode and dilate

evanokeeffe opened this issue a year ago · 5 comments

Trying to integrate this library into some other packages we have that require C++20 for some functions to work.
I tried to compile a simple example . Without C++20 it works, but with it getting a segmentation fault at img_erode = ImgTest.get_erode(msk);

#define cimg_use_tif

#include <CImg.h>
#include < iostream >
using namespace cimg_library;

int main()
{
CImg ImgTest;
ImgTest.load_tiff("float_image.tif");

CImg out(ImgTest);
CImg img_erode(ImgTest);
CImg msk(5,5);

msk.fill(1);

img_erode = ImgTest.get_erode(msk);
std::cout << "Min: " << img_erode.min() << std::endl;
out = img_erode.get_dilate(msk);
std::cout << "Min: " << out.min() << std::endl;

out.save_tiff("V_float.tif");

return 1;
}

Your code does not compile as it is. There's missing #include <iostream> and a template parameter when declaring the CImg variables.

If you use g++, have you tried compiling with option -fsanitize=address ? It gives interesting information about the cause of a crash.

Ah ok, going to try that thank you

Ok ran with the sanitize address flag and I've attached the output below.
