Custom ASAN_OPTIONS set without abort_on_error=1

background: when i want to run AFL . I met this issue.

and either set export ASAN_OPTIONS=abort_on_error=0 nor export ASAN_OPTIONS=abort_on_error=1 doesn't work .

the way to solve it is "export ASAN_OPTIONS='abort_on_error=1:symbolize=0" and then everything is ok. cool.
