I tried to use Address Sanitizer (Xcode 12.4 (12D4e)), but I get this error。 ==985==ERROR: AddressSanitizer failed to allocate 0xffffffffff9fc000 (-6307840) bytes at address 2db624000 (errno: 22) ==985==ReserveShadowMemoryRange failed while trying to map 0xffffffffff9fc000 bytes. Perhaps you're using ulimit -v I run ulimit -v on the terminal. show unlimited I follow this link ASAN_OPTIONS environment variable - https://developer.apple.com/forums/thread/650641?answerId=635010022#635010022 . Please set the ASAN_OPTIONS environment variable with value verbosity=3 (you can do this in Xcode's scheme editor) and launch your app with ASan in Xcode with debugger attached. Setting the environment variable will cause ASan to print out more information about what it's doing when the app starts. When ASan crashes the debugger should still be attached. In the debugger console type bt all and press enter. This should print the stacktrace of the all the running threads in the program. Please attach the entire output to the report. result: ==994==AddressSanitizer: libc interceptors initialized ==994==FindDynamicShadowStart, space_size = 0x00005b003fff || `[0x0002db020000, 0x0002d7ffffff]` || HighMem  || || `[0x0002db624000, 0x0002db01ffff]` || HighShadow || || `[0x0002d0024000, 0x0002db623fff]` || ShadowGap || || `[0x000280020000, 0x0002d0023fff]` || LowShadow || || `[0x000000000000, 0x00028001ffff]` || LowMem   || MemToShadow(shadow): 0x0002d0024000 0x0002da0247ff 0x0002db6e4800 0x0002db623fff redzone=16 max_redzone=2048 quarantine_size_mb=16M thread_local_quarantine_size_kb=64K malloc_context_size=30 SHADOW_SCALE: 3 SHADOW_GRANULARITY: 8 SHADOW_OFFSET: 0x280020000 ==994==ERROR: AddressSanitizer failed to allocate 0xffffffffff9fc000 (-6307840) bytes at address 2db624000 (errno: 22) ==994==ReserveShadowMemoryRange failed while trying to map 0xffffffffff9fc000 bytes.
