Thread: isolation test problem with MSVC (VC2012) / Windows 8

My VC2012 / Windows 8 buildfarm member bowerbird is having frequent 
problems with running the isolation tests. The symptom is that one or 
more output files don't seem to be flushed properly to disk. The odd 
thing is that the Mingw buildfarm member jacana I have on the same 
machine is having no difficulty, and I find it hard to account for the 
difference. In any case, I'm wondering if adding a couple of 
fflush(stdout) calls (at the bottom on main() and exit_nicely()) to 
src/test/isolation/isolationtester.c might help. Does anyone object to 
me trying this?

cheers

I've been wondering what's going on there.

I'd bet against this helping; to believe that it will, you'd have to
explain why we need an fflush here but in every other program exit()
manages to handle that by itself.  Still, it's hard to see what else
to try.
