ACATS tests that fail valgrind check

[Duncan Sands]

I ran all ACATS tests under valgrind (http://valgrind.kde.org/).  Valgrind detected problems with 63 tests.
The tests were compiled using gcc built from CVS date 2005-01-07.  I turned on debugging (-g) in order to
get better backtraces from valgrind.

In the following table, P/F means the ACATS test Passed/Failed.  V means valgrind
detected wrong code.

Comments
--------

Several ACATS failures are compile failures, making it impossible to run the program under valgrind.
These are marked "F ", the same as a program which valgrind thought was ok, but failed the ACATS test.

Some tests which pass the ACATS test when not run under valgrind, fail when run under valgrind.  Correct
programs should run the same whether run under the control of valgrind or not.


All the best,

Duncan.
