log_cb in libretro.c #594
Description
Greetings! Nothing major to report for properly built frontends using this... figured Id report it since ive got a really bare-bones early frontend thing Im writing in DLang and just so happened to have issues cause I was using this as my testing core... in the function emu_step_load_data there are 2 instances where it calls log_cb without the same if (log_cb) checks it has in the other usages ive seen... My thing kept crashing when trying to load a game even though I wasnt explicitly making a call and it was giving an access violation code. seemed to be roughly at that stage where the crashes were happening then I saw 'oh, i dont provide a logger at all yet and the place where its seemingly crashing has a sus lack of checks there'.
