Hangs again - Looks like a GCC bug to me.

At least, 
http://koji.fedoraproject.org/koji/getfile?taskID=410994&name=build.log
ends (or hang) midst of a compilation statement:
...
if g++ -DHAVE_CONFIG_H -I. -I. -I../../.. -I. -I../../../tests/cxts -I../../../otherlibs/highgui -I../../../cxcore/include -I../../../cv/include -I../../../cvaux/include  -DNDEBUG   -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mminimal-toc -MT aoptflowpyrlk.o -MD -MP -MF ".deps/aoptflowpyrlk.Tpo" -c -o aoptflowpyrlk.o aoptflowpyrlk.cpp; \
	then mv -f ".deps/aoptflowpyrlk.Tpo" ".deps/aoptflowpyrlk.Po"; else rm -f ".deps/aoptflowpyrlk.Tpo"; exit 1; fi
In file included from ../../../cvaux/include/cvaux.h:1458,
                 from cvtest.h:51,
                 from aoptflowpyrlk.cpp:42:
[EOF]


=> I am inclined to think ppc64-g++-gcc4.3 has entered a compiler race.
