Tom Lane dd9d78f595 Fix volatile-safety issue in pltcl_SPI_execute_plan(). 
The "callargs" variable is modified within PG_TRY and then referenced
within PG_CATCH, which is exactly the coding pattern we've now found
to be unsafe.  Marking "callargs" volatile would be problematic because
it is passed by reference to some Tcl functions, so fix the problem
by not modifying it within PG_TRY.  We can just postpone the free()
till we exit the PG_TRY construct, as is already done elsewhere in this
same file.

Also, fix failure to free(callargs) when exiting on too-many-arguments
error.  This is only a minor memory leak, but a leak nonetheless.

In passing, remove some unnecessary "volatile" markings in the same
function.  Those doubtless are there because gcc 2.95.3 whinged about
them, but we now know that its algorithm for complaining is many bricks
shy of a load.

This is certainly a live bug with compilers that optimize similarly
to current gcc, so back-patch to all active branches.

PostgreSQL Database Management System
=====================================

This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  This distribution also contains C language bindings.

PostgreSQL has many language interfaces, many of which are listed here:

	http://www.postgresql.org/download

See the file INSTALL for instructions on how to build and install
PostgreSQL.  That file also lists supported operating systems and
hardware platforms and contains information regarding any other
software packages that are required to build or run the PostgreSQL
system.  Copyright and license information can be found in the
file COPYRIGHT.  A comprehensive documentation set is included in this
distribution; it can be read as described in the installation
instructions.

The latest version of this software may be obtained at
http://www.postgresql.org/download/.  For more information look at our
web site located at http://www.postgresql.org/.
