[LLVMdev] [cfe-dev] -fsanitize=address on centos 6.4

Mon Aug 19 11:42:24 PDT 2013

I did a make update.  I thought I was running the newest version of compiler-rt.  But now I can't even get the project to build.  I get the following error:

i386-redhat-linux-gnu-clang++: clang/llvm/include/llvm/ADT/SmallVector.h:544: typename llvm::SmallVectorTemplateBase<T, llvm::isPodLike::value>::iterator llvm::SmallVectorImpl<T>::insert(typename llvm::SmallVectorTemplateBase<T, llvm::isPodLike::value>::iterator, const T&) [with T = const char*]: Assertion `I <= this->end() && "Inserting past the end of the vector."' failed.

I think your compiler-rt checkout is out of date, because r188635 is supposed to fix that exact issue.

This looks like the output of "ld --version". What we need is your glibc version, which is given by "ldd --version".

No need for that, actually, since this is a familiar issue. Sharma, could you please paste the output of "ldd --version" here?

Hi Sharma,
We don't have centos, so we'd ask you for some assistance.
First, could you please run the test with env.var. ASAN_OPTIONS=verbosity=1

Sergey, this CHECK is yours, please take a look.

Hi,

I noticed that the SVN version of clang+llvm does not like -fsanitize=address on centos 6.4.  By "like" I mean it asserts anytime a thread is created.  With errors like:

==18015==AddressSanitizer CHECK failed: clang/llvm/projects/compiler-rt/lib/sanitizer_common/sanitizer_linux_libcdep.cc:251 "((*tls_addr + *tls_size)) <= ((*stk_addr + *stk_size))" (0xf2f7d030, 0xf2f7d000)

If I use the llvm+clang 3.3 version it works properly.
