Previously, __lsan_do_leak_check() was run when using __AFL_LEAK_CHECK,
however this was the incorrect function to use. According to the
documentation: "Subsequent calls to this function will have no effect
and end-of-process leak check will not run".
This meant that if the memory did not leak on the first usage of
__AFL_LEAK_CHECK, subsquent calls to this macro would never do anything.
Likewise, it is not possible to use an LSAN suppression list with
symbolize=0, so instead __lsan_disable and __lsan_enable are used to
'ignore' certain memory allocations where needed.
This caused CMake to complain that the C compiler was set to C++ mode,
causing the CMake configuration step to fail for all targets.
aflplusplus was built with
make source-only -j8 LLVM_BINDIR= AFL_REAL_LD=
* Fix afl-cc to work correctly by default on OSX using xcode
- CLANG_ENV_VAR must be set for afl-as to work
- Use clang mode by default if no specific compiler selected
* Add OSX-specific documentation for configuring shared memory
variable AFL_USE_LSAN.
AFL_USE_LSAN introduces the macro __AFL_CHECK_LEAK() which will check
for a memory leak when the macro is run. This is especially helpful
when using __AFL_LOOP().
If __AFL_LEAK_CHECK() is not used when AFL_USE_LSAN=1 is set,
the leak checker will run when the program exits.
