That testcase produces several compiler warnings on amd64-linux with glibc 2.35. 
E.g.

mallinfo2.c:21:22: warning: format ‘%d’ expects argument of type ‘int’, but 
argument 2 has type ‘size_t’ {aka ‘long unsigned int’} [-Wformat=]

The fix is to use %zu but I'm not sure whether mallinfo2 is defined the same way 
on all supported platforms.
