SEGV on 4 or more test cases with Address Sanitizer #487

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
I link my executable against -fsanitize=address so that I can run it with 
LLVM's Address Sanitizer.  When I define more than 3 test cases, I will 
invariably get a SEGV when gtest gets to the 4th test case.  I tested that this 
holds true even if all of the tests I define across these 4 or more test cases 
are empty stubs.  

Attached is a more complete build and test run output.  Here is the relevant 
address sanitizer error:
ASAN:SIGSEGV

I'm running the tests on Ubuntu 12.04 with the current release of LLVM and 
Clang 3.6.0 from LLVM's official downloads.  I'm using Google Test 1.7.0.

Unfortunately, I seem to get the same result when all tests are in a single 
test case.  See the attached output.  I'm unsure what the cause is.

It looks like this may have actually been a configuration problem on my end.  I 
had my source files linking against -fsanitize=address, but I was not passing 
the parameter to the build of gtest.  When I pass -fsanitize=address to the 
gtest build as well, I don't get this AddressSanitizer error.  It looks like 
it's just necessary for all of the dependencies to be sanitized in order for it 
to correctly understand the memory.  

I believe this can be closed.

I'm glad you found the problem.
Just for the record, gtest has been tested with many of the sanitizer 
configurations, including Address Sanitizer, Memory Sanitizer and Thread 
Sanitizer.
