Title: sf::Font::getTexture Segmentation fault
Post by: aleksav013 on May 30, 2021, 06:40:44 pm

Why does first code work, but the second one gives segmentation fault.
I am providing minimal cpp files as attachments.

gdb:

Code: [Select]

Thread 1 "sfml.out" received signal SIGSEGV, Segmentation fault.

Thanks in advance and sorry for bad looking post, it is my first time on this forum.

The problem was with the fact that default copy constructor was used for defining object of type Game in State class constructor, which was just temporary, and references to Font and Textures were deleted after exiting State class constructor.
