Bugzilla Bug 146669

I've been running sci-mathematics/yacas-1.0.61 without problems ever since it
was stabilized.  However, this week I upgraded to the new/stable GCC version
(4.1.1) and rebuilt my tool-chain/system.  Everything rebuilt without error
except for yacas.

It appears that the following errors are causing the problem:
-------------

It appears this may be an upstream problem based on the errors reported. 
However, I've noticed that bug reporting/handling for the Yacas project seems
quite scattered and unorganized.  I searched the reports listed on the
SourceForge project and found nothing current/related.  I also searched the
developer mailing list and found no such reports.  The developer list was
definitely still active, however -- just no reports of this.

Another note:  I see they just released version 1.0.62 recently.  No ebuild
exists for this version yet and I haven't created one, so I'm not sure if this
would affect the problem at all.

This is probably due to code that mixes 64bit pointers and
32bit ints on x86_64, since I don't see this on my x86 box.
I've just bumped yacas to 1.0.62 in portage cvs; please give it a
shot and let me know if this issue has been fixed in the most recent
version (Unfortunately, I didn't notice anything related in the changelog).

Thanks,
Markus

Agreed, I believe this is exactly the problem.

Well, well...  I just tried the new ebuild and it built perfectly.  The
application itself seems to be functioning properly as well.

Thanks VERY much for taking the time to investigate a little and add the newer
ebuild.  It seems someone around the Yacas project has been fixing their
pointers, even if they didn't mention it in the changelog. :-)

Again, thanks.
