[Bug libc/10325] New: destructor of FILE handles created by fopencookie() not called on exit.

[rixed at happyleptic dot org]

C standard states that all opened FILEs are closed (hence output streams
flushed) when the programs calls exit() or returns from main.

So, one would expect that the close function of a FILE created by fopencookie
should also be called at program exit, which is not the case.

------- Additional Comments From drepper at redhat dot com  2009-10-30 07:18 -------
This wasn't in the design.  The system doesn't know anything about the actual
implementation.  Perhaps some of the resources needed for the cookie functions
is already gone.  It's not safe to try to close the FILE.  Aside, there might be
code out there which depends on the current behavior.  It'd different if from
day one this requirement would have existed.

And whatever ISO C says doesn't apply here because cookie streams are not in ISO C.
