RHBA-2011:0965 - Bug Fix Advisory

Topic

Updated graphviz packages that fix several bugs are now available for Red Hat
Enterprise Linux 6.

Description

Graphviz is graph visualization software used to represent structural
information as diagrams, abstract graphs or networks.

These updated graphviz packages provide fixes for the following bugs:

• Several links in the Graphviz Documentation Index file led to nonexistent or

incorrectly named files. This update fixes these links so that their targets
resolve correctly. (BZ#624658)

• The graphviz test suite was disabled on the PowerPC, 64-bit PowerPC and

SPARC64 architectures due to unexpected terminations with segmentation faults.
The test code used in the test suite did not set the TextLayout plugin
correctly, which led to the crash of the test suite. This has been fixed and the
test suite passes on all architectures. (BZ#624690)

• Prior to this update, the About dialog box displayed "<unknown>" instead of

the real name of the DotEdit utility. This has been fixed and the name is now
displayed correctly. (BZ#640247)

• When using the graphviz utility with PHP, the gv.so module did not load and

displayed the following error message:

/usr/lib64/php/modules/gv.so' - /usr/lib64/php/modules/gv.so: undefined
symbol: zend_error_noreturn in Unknown on line 0

This was caused by the SWIG tool which used the zend_error_noreturn() function
to build the PHP module. SWIG has been modified and the bug no longer occurs.
(BZ#679715)

All users of graphviz are advised to upgrade to these updated packages, which
fix these bugs.
