[Bug c++/42938] New: ICE with 4.4.2 on MIPS

[manuel dot montezelo at gmail dot com]

The package OpenSceneGraph v2.8.2 fails to build with gcc 4.4.2 in the Debian
farm, for MIPS architecture:

https://buildd.debian.org/fetch.cgi?&pkg=openscenegraph&ver=2.8.2-1&arch=mips&stamp=1264018410&file=log

The error line:
.../osgmultitexturecontrol/osgmultitexturecontrol.cpp: In function 'T*
findTopMostNodeOfType(osg::Node*) [with T = osgTerrain::Terrain]':
.../osgmultitexturecontrol/osgmultitexturecontrol.cpp:84: internal compiler
error: Segmentation fault

The file in question:
http://www.openscenegraph.org/projects/osg/browser/OpenSceneGraph/trunk/examples/osgmultitexturecontrol/osgmultitexturecontrol.cpp

This project was building OK with previous version of the package (2.8.1) and
gcc 4.3.3 on the same architecture:
https://buildd.debian.org/fetch.cgi?&pkg=openscenegraph&ver=2.8.1-1.1&arch=armel&stamp=1251997885&file=log

This doesn't seem to be a problem for the rest of the architectures, except for
another building problem in ARMEL which maybe it's unrelated to the compiler,
or it's not the same problem anyway:
https://buildd.debian.org/fetch.cgi?&pkg=openscenegraph&ver=2.8.2-1&arch=armel&stamp=1263767284&file=log

For the logs of the rest of building attempts in last package versions and all
Debian supported kernel/architectures:
https://buildd.debian.org/build.cgi?pkg=openscenegraph

Neither I nor the official developer who uploaded the package have access to
the machines to provide you the intermediate generated files to help debugging
the problem or anything, nor to test in MIPS architecture with newest GCC
versions.  All the versions of packages with their private Debian patches and
everything is available to download, of course.
