Hi there,

I also run into this problem with gcc 4.8, gcc 4.9 and also gcc 5. Are there any news on this subject? I just switched from Linux to OSX/Macports and this one is a nasty drawback for code development.

Cheers

Sorry, it doesn’t seem that anyone’s had the time or inclination to look into this yet. I’ll try to investigate soon.

In any case, please note that ThreadSanitizer ​is not really supported on OS X.
