Browse Source 
Only used, when asserts are enabled.

Fixes an unused-variable warning with GCC 8:
 ../../../src/intel/tools/aubinator.c: In function 'ensure_phys_mem':
 ../../../src/intel/tools/aubinator.c:209:11: warning: unused variable 'ftruncate_res' [-Wunused-variable]
        int ftruncate_res = ftruncate(mem_fd, mem_fd_len += 4096);
            ^~~~~~~~~~~~~
