[cairo-commit] cairo/test .valgrind-suppressions, NONE, 1.1 Makefile.am, 1.63, 1.64

[Carl Worth]

Committed by: cworth

Update of /cvs/cairo/cairo/test
In directory gabe:/tmp/cvs-serv7919/test

Modified Files:
	Makefile.am 
Added Files:
	.valgrind-suppressions 
Log Message:

        * test/.valgrind-suppressions: Add valgrind suppressions for
        libpng/libz use of uninitialized data. There are clearly bugs here
        that are not cairo's fault as zeroing the buffer before writing
        the png image actually causes more errors(\!). And, notably,
        setting all the data to random bytes usually makes the errors go
        away.

        * test/Makefile.am: Change the check-valgrind target to include
        the .valgrind-suppresions file and to tee output into
        valgrind.log.
