GCC Address Sanitizer - 将库函数列入黑名单（特别是 boost::test）

Question

All of my unit-test code is based around boost::test . I have just tried the GCC Address sanitizer and it reports some issues with boost::test:

==25309==ERROR: AddressSanitizer: heap-use-after-free on address 0xf5801344 at pc 0x8259412 bp 0xff9966c8 sp 0xff9966bc
READ of size 4 at 0xf5801344 thread T0
#0 0x8259411 in boost::unit_test::framework::run(unsigned long, bool)     ../common/lib/boost/boost/test/impl/framework.ipp:450
#1 0x82732f7 in boost::unit_test::unit_test_main(bool (*)(), int, char**) ../common/lib/boost/boost/test/impl/unit_test_main.ipp:185

#4 0x8238680 (/home/marpashl/lte/sw/build/x86/bin/framework_unit_test+0x8238680)

I would like to hide this message (as it is for a known error in a test library) so that I only see issues within my own code.

Is there a way of doing this with GCC?

Note Compiler version GCC: /opt/gcc-x86-4.9.2/bin/c++

I found that with CLANG files can be blacklisted using -fsanitize-blacklist=blacklist.txt but this is not currently available for GCC.

Answer 1

If the sanitize-blacklist is not available, but you have access to the source code, you can exclude individual functions from being sanitized using a function attribute:

It is supported by Clang (3.3+) and GCC (4.8+). You can define the following macro:

#if defined(__clang__) || defined (__GNUC__)
# define ATTRIBUTE_NO_SANITIZE_ADDRESS __attribute__((no_sanitize_address))
#else
# define ATTRIBUTE_NO_SANITIZE_ADDRESS
#endif
...
ATTRIBUTE_NO_SANITIZE_ADDRESS
void ThisFunctionWillNotBeInstrumented() {...}

See this page for more details.

A bit late to the party, but for what it's worth: You can also pass the blacklist file as an option via an environment variable to the sanitizer. Which is useful if you do not have access to the source code eg

LSAN_OPTIONS=suppressions=blacklist.txt ./unit-tests
