[Debian-astro-maintainers] Bug#859777: saods9: Internal error after enabling horizontal or vertical graph

[Ole Streicher]

Package: saods9
Version: 7.5+repack1-1
Severity: important
Forwarded: https://github.com/SAOImageDS9/SAOImageDS9/issues/30

When I enable one of the graphs in the "View" menu, I get an error box
"An internal error has been detected [OK]" as soon as the mouse is in
the image area, but outside of the borders of the FITS image.
This window immediately re-appears as long as I don't move it to a place
where the cursor is not left over such an area after the error box
disappears.

On the Debian build, I also get a segmentation fault when I am in within
the borders of a FITS image, when calling Base::bltCut(char*, char*,
Coord::Orientation, Vector const&) () in frame/frblt.C line 947.

This does not appear in the original built. The major difference here
are that Debian uses specific build flags to enable hardening
(-fstack-protector-strong -D_FORTIFY_SOURCE=2) and the we use tkblt as a
separate tcl package.
