Available flags for AddressSanitizer:
	quarantine_size
		- Deprecated, please use quarantine_size_mb.
	quarantine_size_mb
		- Size (in Mb) of quarantine used to detect use-after-free errors. Lower value may reduce memory usage but increase the chance of false negatives.
	thread_local_quarantine_size_kb
		- Size (in Kb) of thread local quarantine used to detect use-after-free errors. Lower value may reduce memory usage but increase the chance of false negatives. It is not advised to go lower than 64Kb, otherwise frequent transfers to global quarantine might affect performance.
	redzone
		- Minimal size (in bytes) of redzones around heap objects. Requirement: redzone >= 16, is a power of two.
	max_redzone
