CRT Assertion was totally disabled before, but recently was enabled,
and workarounds were patched for problematic functions. (ex: fdopen and 
dup) Probably this *patch* is not perfect. See 

I'm now +3/4 for the idea disabling assertion by default,
and enabling by startup option or environment variable. (Or enabling
by default and disabling by environment variable?)
