CONFIG_ASAN
¶
Build with address sanitizer
Type: bool
Help¶
Builds Zephyr with Address Sanitizer enabled. This is currently
only supported by boards based on the posix architecture, and requires a
recent-ish compiler with the -fsanitize=address
command line option,
and the libasan library.
Note that at exit leak detection is disabled for 64-bit boards when GCC is used due to potential risk of a deadlock in libasan. This behavior can be changes by adding leak_check_at_exit=1 to the environment variable ASAN_OPTIONS.
Defaults¶
No defaults. Implicitly defaults to n
.
