another testcase
On x86_64-linux, when compiled with "gcc-7 -O2 -fsanitize=address" this
testcase prints nothing. With "gcc-7 -O2 -fsanitize=address
-fsanitize=undefined" this slightly confusing message is output:
test-asan1.c:36:29: runtime error: load of address 0x000000602660 with
insufficient space for an object of type 'inttype'
0x000000602660: note: pointer points here
