New issue 356 by [email protected]: can not mask function in closed
source library
https://code.google.com/p/address-sanitizer/issues/detail?id=356
What steps will reproduce the problem?
1. Compile attached example: gmake
2. Run: LD_LIBRARY_PATH="./" ./app
3. it stops on function "f"
What is the expected output? What do you see instead?
At least not abort/exit after call function "f"
What version of the product are you using? On what operating system?
I try clang 3.5.0 and gcc 4.9.2
I used close source library (linux shared library) with my application,
that I can not fix/recompile. I want ignore errors from it (sometimes it
calls strncpy with the same pointers as input and output).
I tried add __attribute__((__no_sanitize_address__)) to its definitions,
I tried add __attribute__((__no_sanitize_address__)) to my function (which
compiled with -fsanitize=address) that call function from close source
library.
I tried clang "-fsanitize-blacklist=blacklist.txt", and in blacklist.txt I
mentioned bad function from close source library, plus my function with
call bad function from close source library.
Neither of these variants can mask problem, and allow me to debug my code.
In attachment file is simple gnu make based project, that demonstrate
problem.
