<br>
</div>I have used them with clang. They are awesome. They are pretty bleeding edge though, and have some false positives.<br>
<br>
The most mature of the -fsanitize flags is the undefined behaviour sanitizer (ubsan). I tried enabling ubsan on my Rogue7 ITK dashboard some months ago, but they report a gazillion errors, many from GDCM and vxl. I turned my attention to fixing VTK since its code is easier to work with (IMHO: templates=ugh).<br>
<br>
Address sanitizer (asan) probably won't find too much since you already use valgrind, though asan can find overruns of stack and globals, whereas valgrind only checks heap memory.<br>
<br>
Thread sanitizer (tsan) only works with linux right now, so I've only tried it a little bit, but it's promising. But fixing tricky threading issues IMHO should come only after we are valgrind-, ubsan-, and asan-clean.<br>
<br>
I'll create a 'torture' dashboard on Rogue7 and we can enable one ubsan flag at a time...<br>
<br>
Cheers,<br>
