Bug#640502: freecad: FreeCAD crashes when zooming out on large imported STL file

[David Goodenough]

Package: freecad
Version: 0.11.4446-dfsg-2+b1
Severity: normal

Following the import of a large STL file (I have tried several that I
downloaded from thingiverse.com) I tried to zoom out to view the whole item.  
Whether I zoomed incrementally, or asked for the view to include the whole 
item, FreeCAD crashed with:-

freecad: intel_tris.c:128: intel_extend_inline: Assertion `intel->prim.flush 
== intel_flush_inline_primitive' failed.

I can supply a sample STL file (or point to a download site) but it happened 
with all the large ones I tried, so I do not think it is STL file specific.

It does look (from the file name) that this might be graphic card specific (I 
have an Intel chip in my laptop:-

00:02.0 VGA compatible controller: Intel Corporation 82852/855GM Integrated 
Graphics Device (rev 02)
00:02.1 Display controller: Intel Corporation 82852/855GM Integrated Graphics 
Device (rev 02)
