I am trying to build the cylinder example from the doc. I use cmake then open the project in Visual Studio. I am able to build the project but when I run it in debug mode I get the following error :
Exception thrown at 0x00007FFB241E4FD9 in main.exe: Microsoft C++ exception: std::bad_alloc at memory location 0x0000001D47EFF250.
It comes from the colors->SetColor("BkgColor", bkg.data());. If I remove this line it also happens with other functions trying to set the color.
When I run the program in release mode, it runs fine.
What do you think is going wrong in debug mode ?
