tests_openssl.x.bc misses one function after protection transformation #25

Open mr-ma opened 6 years ago

mr-ma commented 6 years ago

SC patcher fails to find a function in the binary, which is actually not there! ERR: failed to find function:sym.yajl_internal_free00 I compared the original bc, after coverage improvements (extract and clone, with the transformed one (sc+oh). The latter does not contain yajl_internal_free00 function. My guess is that since this function does not have any call site, it is being deleted by LLVM. Both bc files are uploaded here

This actually happens for the following function too. ERR: failed to find function:sym.default_illegal_callback_fn00

GDB is also failing to patch some asserts, because it doesn't see them.
