I get the exact same segmentation fault when running x-povray on my alpha
linux
box!
I just compiled the povray3.1g source on a dec alpha (ev5 cpu) running
redhat 6.1.
Everything compiled just fine using gcc with the generic unix optimization
switches suggested in the makefile.

The core dump occurs at the rendering stage, while processing the second
scan line
of whatever I try to render.  The error does NOT occur if
Output_to_File=false
 in my .povrayrc file, that is, I can get beautiful images on-screen, just
not on my harddrive! The error does not care which
filetype the output image is.  Also, an output file is created, but is blank

Unfortunately, I don't know c (just fortran--I'm impaired by my chemical
engineering training) so I'm not
sure I want to attempt to debug any povray code at this point.  Hopefully,
my description can narrow down the location of
the problem a bit for those povray.unix gurus out there.  Any help much
appreciated--especially if someone successfully uses povray on an alpha
linux box.

Well, I just solved my own problem:
The file buffer options were not set in the .povrayrc default file--after I put
in these entries I have not had core dumps when outputting to files:

Buffer_output=true
Buffer_size=100

[any Buffer size worked fine, even =1]
