Updated fontconfig packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The fontconfig packages contain the font configuration and customization library, which is designed to locate fonts within the system and select them according to the requirements specified by the applications.
- Previously, when the font cache file was stored on a Network File System (NFS), the fontconfig library sometimes did not handle mmap() calls correctly. As a consequence, applications using fontconfig, for example the GNOME terminal, could terminate unexpectedly with a bus error. With this update, the FONTCONFIG_USE_MMAP environment variable has been added to handle the mmap() calls regardless of the file system, and these calls are no longer used if the cache file is stored on an NFS. As a result, the bus errors no longer occur in the described situation.
- Previously, the 25-no-bitmap-fedora.conf file name contained the word 'fedora', although file names in Red Hat Enterprise Linux are not supposed to include the word 'Fedora'. With this update, 25-no-bitmap-fedora.conf has been renamed to 25-no-bitmap-dist.conf, and the spec file has been updated.
Users of fontconfig are advised to upgrade to these updated packages, which fix this bug.
