Fixed bug 4366 - Compile throws a warning on RPI (Raspbian Stretch)

midwan

When trying to compile on a Raspberry Pi 3, running Raspbian Stretch (fully updated), a warning appears:

/home/pi/projects/SDL/src/test/SDL_test_memory.c: In function ‘SDL_TrackAllocation’:
/home/pi/projects/SDL/src/test/SDL_test_memory.c:112:109: warning: format ‘%llx’ expects argument of type ‘long long unsigned int’, but argument 5 has type ‘unw_word_t {aka unsigned int}’ [-Wformat=]
                 snprintf(entry->stack_names[stack_index], sizeof(entry->stack_names[stack_index]), "%s+0x%llx", sym, offset);
