In my case, this loop was an endless loop. line.length() was always 0 and the
Stream.eof() never returned true (at least I checked this until line_number =

I was interested in which file was actually parsed here:

(gdb) print conf_name
$7 = (const std::locale::string &) @0x92f7f8: {
  static npos = 18446744073709551615,
  _M_dataplus = {<std::allocator<char>> = {<__gnu_cxx::new_allocator<char>> =
{<No data fields>}, <No data fields>},
    _M_p = 0x92f928 "/home/bioinfp/jang/.povray/3.7/povray.conf"}}

And now it gets funny:

ls -ahl /home/bioinfp/jang/.povray/3.7/
1.5K drwxr-xr-x 2 jang bioinfp 2 2011-06-08 15:50 povray.conf/

povray.conf was a directory in my case. I removed it, restarted 'make check' and
the test worked fine (X window opened..."POV-Ray finished").

I think the path /home/bioinfp/jang/.povray/3.7/ existed due to some former
tries of myself to 'make install' povray. I have no idea why this povray.conf
existed as a _directory_ -- it may be my fault from earlier times. But you maybe
could add some more dir/file checking so that povray never tries to read lines
from a directory :-)

I removed ~/povray and invoked 'make install'. Now, there is only one small
problem left:

Creating data directories...
Copying data files...
Creating documentation directories...
Copying documentation files...
Creating user directories...

make[1]: Leaving directory `/home/bioinfp/jang/sumpf/povray-3.7.0.RC3'
make: *** [install-recursive] Error 1

The installation works, but what does the make script try to do with the
permissions? And yes, my home directory is a mounted NFS.

Thanks for your help,
