Description Stefan Dirsch 2005-07-31 02:55:35 UTC
I just tried to update libfreetype2 to 2.1.10. Unfortunately, the Xserver 
freetype module uses some internal libfreetype2 interface, which changed in 
the new version of libfreetype2. This results in Xserver crashes and is 
related to embedded bitmap support in libfreetype2. 
More details could be found here: 
I attach a small patch, which avoids the crashes for me - and disables  
embedded bitmap support completely. :-(

After reverting some changes in libfreetype 2.1.10 (I'll attach another patch 
for this) the Xserver no longer crashes (also without the Xserver patch 
above). Since I'm quite sure, that these changes were intentional the 
libfreetype patch should only be used as workaround for now. The libfreetype 
developers didn't comment yet. :-(

Any plans on merging these patches?

Marking broken (status null/blank) bugs in xorg with no activity in a long time as fixed. Please reopen if you think it's necessary, but first do a search if a similar bug report is already filed and in a NEW/ASSIGNED state. These bugs do not currently show in most search results as they do not have any status.

Yes, I think these patches are obsoleted by current X.Org/freetype2 versions. At least SUSE no longer uses these patches for X.Org/freetype2.
