Hi Alexey,

thanks, fixed in SVN 697.

Thanks, now it is better and I was able to start compilation with "make
develop". However I quickly stuck with the compilation error:

Hi Alexey,

make clean

before make

has the same effect. If you have the autotools installed (looks like you have) then the
following should work as well:

autoreconf
./configure
make develop

 Hi,

I've just removed local version and checked out again. Did ./configure
and make, and the bug still there.
I cannot build with "make develop" since it complains about absense of
aclocal-1.14 (I have aclocal installed).

However I'm compiling and running on OSX 10.10.5

Juergen Sauermann <address@hidden> writes:

 Hi Alexey,

Hm, it works on my machine. Did you recently upgrade from SVN?
It can happen that changes in header files are not detected if ./configure is called without arguments
and then the sources are uodated from SVN, Please try the following:

make clean develop

and see if the problem remains.

 Hi,

I'm studying the paper http://archive.vector.org.uk/art10501380

Here defined 3 functions:
⍝ simple sort
Sort←{⍵[⍋⍵]}

R←∇triples N;all;i
⍝ All possible triples of numbers 1..9
i←⍳9
all←,i∘.,i∘.,i
R←(N=+/¨all)/all

⍝ remove those triples which contain repeating entries or not unique
clean←{ ∪Sort¨ ({⍵≡∪⍵}¨⍵)/⍵ }

And then try to run
clean triples 4
lead to crash(assertion).
