--- Comment #6 from Steve Ellcey <sje at gcc dot gnu.org> --- I still haven't been able to reproduce this. I have been trying to do so with the gcc-5-branch. Aurelien, what host GCC version are you using when you build a cross compiler? I am building on Ubuntu 12.04 with GCC 4.6.3 and am building the cross compiler as a 64 bit executable.
