I don't think this has anything to do with exceptions. Without a clearer 
picture (ie source or self contained test case) of what is going on, I 
can't really say.

Note that you can also use CXXFLAGS='-fno-exceptions' to disable 
exception handling, if you believe this is at issue.

There should not be anything required except using -pthread. You 
shouldn't have to use __USE_MALLOC at all.

No.
