3.2.3 works, CVS HEAD as well.

$ g++ -c -g -mcpu=i686 -march=i686 -ffast-math -fomit-frame-pointer -O3
-fno-rtti -c -fPIC cvfundam.ii
cvfundam.cpp: In function `int icvCubicV(double, double, double, double*)':
cvfundam.cpp:2187: internal compiler error: in emit_move_insn_1, at expr.c:3510
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

omitting "mcpu=i686 -march=i686" or omitting "-ffast-math" seems to be a workaround.

Confirmed, some how a target problem as in ix86_split_long_move, it is spliting them into two 
constants but nothing has changed for 3.4 with respect to ix86_split_long_move.

This is a dup of bug 13634 which has a simple testcase.
