Description midwan 2018-11-07 18:04:32 UTC 
This occurs in both 2.0.9 and the current tip from Mercurial:

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);
Comment 1 Christer Solskogen 2018-11-08 10:17:16 UTC 
This only happens if HAVE_LIBUNWIND_H is defined (and alas: if the user have /usr/include/libunwind.h)
Comment 2 Sam Lantinga 2018-11-13 00:43:30 UTC 
Fixed, thanks!

We need the larger size in the print statement to cover 64-bit architectures.
