[Insight-developers] Define _GLIBCXX_DEBUG on dashboard?

[Bradley Lowekamp]

Hi,

I am looking through more gcc debug flags and I have come across a couple interesting new ones with gcc 4.8:

-fsanitize=address
Enable AddressSanitizer, a fast memory error detector. Memory access instructions will be instrumented to detect out-of-bounds and use-after-free bugs. See http://code.google.com/p/address-sanitizer/ for more details. 
-fsanitize=thread
Enable ThreadSanitizer, a fast data race detector. Memory access instructions will be instrumented to detect data race bugs. See http://code.google.com/p/data-race-test/wiki/ThreadSanitizer for more details. 


It looks like they are ported from clang/llvm projects. They looks quite useful!

I'd be curios if any one has tried them out in clang or gcc, and what they think of them.
