Seems like it crashes in the SDL_SetVideoMode() function in SDL. Some
googling found a similar bug report for Wesnoth:

Does the attached little program also crash? You can compile it with
"gcc `pkg-config --cflags sdl` `pkg-config --libs sdl` -o sdl-crashtest
sdl-crashtest.c"
#include <stdio.h>
#include <SDL.h>
int main() {
if (SDL_Init(SDL_INIT_VIDEO) < 0) {
printf("SDL_Init() failed.\n");
exit(1);
}
if (SDL_SetVideoMode(0, 0, 0, SDL_SWSURFACE | SDL_ANYFORMAT | SDL_RESIZABLE) < 0) {
printf("SDL_SetVideoMode() failed.\n");
exit(1);
}
printf("Video mode change successful.\n");
return 0;
}
