    _______________________________________________________

Details:

This patch corrects two problems observed in the 1.11.21 release of CVS on
AIX systems.  The routine affected is stdio_buffer_shutdown() in
src/buffer.c.  Two issues are corrected.

Firstly, the assertion if fstat() fails is removed -- on an AIX system,
fstat() will return -1 if the client has gone away unexpectedly.  This being
an unfortunately common use case, an assertion for this state is
undesirable.

Secondly, this routine contained calls to error() using 1 as the first
parameter, which instructs the server to shut down.  However, this routine is
active because the server is shutting down, and thus the 1 parameter causes an
infinite recursion.  These calls have been changed to use 0 as the first
parameter.
