g++ -v output:
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ../gcc-4.2.0/configure --prefix=/opt/gcc4.2.0
Thread model: posix
gcc version 4.2.0
using the following compilation flags:
g++ -Wall -Werror -ansi -pedantic -Wno-long-long -pipe -fmessage-length=0
-funit-at-a-time -maccumulate-outgoing-args -fvisibility-inlines-hidden
-fno-strict-aliasing -O3 -fsee -momit-leaf-frame-pointer -fmodulo-sched

-ftree-vectorize -fbranch-target-load-optimize2 -march=i686 -mfpmath=sse -msse
./bug.cpp
creates illegal code.
I think movapps recieves a misaligned memory address. Omitting
"ftree-vectorize" from the compiler flags solves the problem.
thanks.
