QASan: custom QEMU which detects memory errors using clang's AddressSanitizer

[…]I created QASan (QEMU-AddressSanitizer), a fork of user-mode QEMU that introduce AddressSanitizer for heap objects into QEMU. QASan not only enables AddressSanitizer on COTS x86/x86_64/ARM/ARM64 binaries on Linux/*BSD but allows also the instrumentation of code generated at runtime (e.g. JIT) that is, of course, not supported by source-level ASAN. Note also that at the time of writing AddressSanitizer doesn’t support ARM/ARM64 on Linux and QASan enables that for this class of binaries.[…]
