        I looked at the code. It contain really a huge numner of
        errors. Even trying to fix this bug will leave open a huge
        number of other bugs...

        The code it's really old, not maintained and probably it
        requires a rewriting that I have no time to do alone.

        For the moment I will orphan the package, probably it could be
        safely removed from the archive, I think.

        Regards

Package: euler
Followup-For: Bug #336515

I am unable to reproduce this bug with euler-1.61.0 - i.e. all of the
graphs in the autodemo.en are displayed on my system.

Perhaps this bug no longer exists in the 1.61.0 version of euler?

Hi tony,

On my system euler freezes at autodemo.en's "A trefoil knot". This always
happens when no other demo was executed before. If some other demos were
executed before running autodemo.en, euler sometimes shows all of
autodemo.en's graphs. If I run however the 3d.en demo before autodemo.en,
euler segfaults at the "A trefoil knot" with:

(gdb) run
Starting program: /usr/bin/euler
[Thread debugging using libthread_db enabled]
[New Thread 0xb754a6b0 (LWP 12251)]

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0xb754a6b0 (LWP 12251)]
0x08094b4c in searchvar ()

And the function searchvar() is in stack.c and enfolds line 812. So I can
occasionally reproduce this bug.

Grüße,
Frank
