Red Hat Bugzilla – Bug 215760
Bug in rendering ASCII space character
Last modified: 2007-11-30 17:07:37 EST
+++ This bug was initially created as a clone of Bug #214048 +++
Description of problem:
freetype returns an "invalid argument" error (6) when rendering character code
32 (if there are no strokes in the glyph) because it leads to allocating a
0-length block of memory and ftutil.c considers that an error.
Version-Release number of selected component (if applicable):
Always. An example of a program that is affected by this bug is tuxtype2, which
segfaults immediately on startup (trying to dereference a null pointer).
Steps to Reproduce:
1. Install tuxtype2 from the Fedora 6 Extras collection
2. Run tuxtype2
Program received signal SIGSEGV, Segmentation fault.

Behdad, I guess we need this fix in RHEL5, too ?
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release. Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release. This request is not yet committed for
Is there another way to reproduce this? I tried to rebuild tuxtype2 for RHEL5,
but had missing BRs.
