show_buttons core dumping

milnak commented 3 years ago

I'm seeing a core dump when run. I can't find the source for /usr/local/bin/show_buttons -- did some disassembly and it appears to do:

SDL_ShowCursor
SDL_SetVideoMode
IMG_Load
rotozoomSurfaceXY
SDL_CreateRGBSurface
etc.

but im not seeing anything obvious there (maybe an SDL crash?)

parameters being sent are:

$ll_path = /root/.lemonlauncher $w = 1510 $h = 240

show_buttons $ll_path/loadingen.png $w $h 2000 0

found core dumps in /var/lib/systemd/coredump, but I wasn't able to open in gdb.

screen passed to SDL_Flip is NULL, so it's crashing.

mitigation for now is to edit regamebox.conf and use SHOW_LOADING_SCREEN=0

works in 3.2
