...CMake build check for -funwind-tables was failing (because of some missing link libraries), so compiler-rt wasn't being built with that flag, which in turn led to all backtraces failing with an error like the following: ==21748==AddressSanitizer CHECK failed: …/compiler-rt/lib/sanitizer_common/sanitizer_stacktrace.cc:116 "((count)) < ((size))" (0x0, 0x0) <empty stack> I'm not entirely sure why omitting -funwind-tables would result in this outcome. I guess stack walking on ARM relies on those tables; I was building with -fno-omit-frame-pointer, but perhaps frame pointer walking isn...

Hello, I have been working on porting ASan to AArch64. I am building compiler-rt in "standalone mode" targeting aarch64. My build is successful, but I get the following runtime error when I run an ASan enabled executable through qemu-aarch64: ==29184==Parsed ASAN_OPTIONS: verbosity=1 ==29184==AddressSanitizer: failed to intercept '__isoc99_printf' ==29184==AddressSanitizer:
