Functions with non-empty exception specifications aside, unless that 
exception was explicitly "declared" to be propagated on join (whether 
a function has some non-void return value doesn't really matter, IMO), 
I'd "return" something along the lines of EXIT_FAILURE. ;-) ;-)

Well, actually, abort() [standard terminate() method/handler] will 
take care of it: < quoting ISO C standard, "99" version though >

"The abort function causes abnormal program termination to occur, 
 unless the signal SIGABRT is being caught and the signal handler 
 does not return. Whether open streams with unwritten buffered 
 data are flushed, open streams are closed, or temporary files 
 are removed is implementation-defined. An implementation-defined 
 form of the status unsuccessful termination is returned to the
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 
 host environment by means of the function call raise(SIGABRT)."
