 It seems that its a ubuntu 8.04 bug!!!!
On ubuntu 7.10 the test is running correctly.

 I can reproduce this by doing the following with a VTK 5.4.2 Python 2.6.2 build on Ubuntu 8.04 x86:

import vtk
ta = vtk.vtkTextActor3D()
ta.SetInput('test text')
ta.GetBounds()

yields:
Program received signal SIGSEGV, Segmentation fault.

vtk_freetype_FTC_CMapCache_Lookup (cmap_cache=0x825f8c8,
    face_id=<value optimized out>, cmap_index=0, char_code=108)
    at /home/cpbotha/build/jwd/archive/VTK/Utilities/vtkfreetype/src/cache/ftccmap.c:394
394 cmap = face->charmaps[cmap_index];

Have you managed to work-around or fix this somehow?

 Nope,

the crash is in the test suite, and i thought that it is helpful reporting this bug.

 I finally solved this problem by patching the VTK 5.4.2 vtkfreetype CMakeLists to build only that module with -O0 (no optimisation). The patch is here:
http://code.google.com/p/devide/source/browse/trunk/johannes/patches/vtkfreetype_segfault.diff [^]

This is only necessary on Ubuntu 8.04 and Ubuntu 8.10, and not on Ubuntu 9.04. It seems that on the older versions, the GCC optimisation breaks FT caching code.
