--- Comment #1 from Kostya Serebryany <kcc at google.com> ---
This is expected. 
>From https://code.google.com/p/address-sanitizer/wiki/Flags (just added that):

disable_core     0/1     Disable the core dumper. Since asan consumes many
terabytes of virtual memory on 64-bit, dumping core is unwise. Default: 0 on
32-bit and 1 on 64-bit.

% clang -fsanitize=address setrlimit.c ; ./a.out 
ret: -1, errno: 1, message: Operation not permitted
% clang -fsanitize=address setrlimit.c ; ASAN_OPTIONS=disable_core=0 ./a.out 
ret: 0, errno: 0, message: Success
% clang -m32 -fsanitize=address setrlimit.c ; ./a.out 
ret: 0, errno: 0, message: Success
% 


Why would you want to have a 20Tb core file on your disk?
