For some reason, the __*san_default_options are not being used from libafl_targets. Probably an extension of some of the whole-archive problems we've been having. We need to add this for correct error handling behaviour, or the fuzzing program may terminate unexpectedly.

If you need a workaround for this:

export ASAN_OPTIONS='abort_on_error=1:detect_leaks=0:malloc_context_size=0:symbolize=0:allocator_may_return_null=1:detect_odr_violation=0:handle_segv=0:handle_sigbus=0:handle_abort=0:handle_sigfpe=0:handle_sigill=0'
