[OctDev] delaunayn makes octave crash

[Alexander B. <ab...@ma...>]

Hi all,

I have a problem with delaunayn under octave 2.9.5. The following code 
make octave crash:
n = 3;
x = repmat(reshape(1:n,[n 1 1]),[1 n n]);
y = repmat(reshape(1:n,[1 n 1]),[n 1 n]);
z = repmat(reshape(1:n,[1 1 n]),[n n 1]);
P = [x(:) y(:) z(:)];
T  = delaunayn(P);

I have this problem with delaunayn from fedora core 5 
(octave-forge-2006.03.17-4.fc5) as well as with the current CVS version 
of octave-forge (I changed the print_usage() manually to 
print_usage('delaunayn') to compile with octave 2.9.5 instead of octave 
CVS).

The delaunayn function crashes at the line "qh_freeqhull(!qh_ALL);"

Any ideas ? Can anybody confirm this bug?

Some information about my system:
AMD - 64
gcc 4.1.1
qhull-2003.1-5.fc5

Cheers
Alex
