General / Re: SFML disables error output on exception termination (c++)

These are debugging exceptions. The unrecoverable ones you expect to throw when reading invalid data or while developing. Missing input files, invalid data format and such.

Of course I could just put a try/catch around my entire main loop and print but I still want to find out why this happens.

General / SFML disables error output on exception termination (c++)

« on: November 19, 2021, 05:09:17 pm »

I'm running MinGW (MSYS2) and fairly recently (a couple of months I'd guess) I started having a problem where exception output is not printed on termination.

Minimal example:

#include <SFML/Graphics.hpp>

int main() {
    sf::RenderWindow window(sf::VideoMode(1000,1000), "Whatever");
    throw std::invalid_argument("BLARGH");
}

I expect this to output and terminate

terminate called after throwing an instance of 'std::invalid_argument'
  what():  BLARGH

This works just fine on Linux as well as if I run it via explorer (the "This process has stopped responding" popup opens and the exception output is printed in the terminal in the background). Removing the sf::RenderWindow line also fixes the issue. Normal printing to both stdout and stderr is unaffected.

I cant think of anything in particular that has changed within that timeframe. No MSYS/SFML updates.

I realise this may not be an actual SFML issue (I'm looking into things on MinGW forums as well) but since opening an SFML window manages to consistently trigger it I was hoping anyone here might be able to help me figure out what is causing this issue.
