Fix format specifier in call to INFO macro

Improper use of format specifiers for arguments of type intptr_t and size_t
raises warnings at compile time. Compilation breaks when GCC's -Werror flag is
set, which is the default. By using the appropriate format specifiers, no
warnings are raised and compilation succeeds.
