Failing preprocessed source.
gcc ICE in alpha_handle_trap_shadows, at config/alpha/alpha.c:8724 seen with
the attached preprocessed source (being a source file from python-scipy) when
compiling at -O2 with both -mieee and -mcpu=ev4 on gcc git master and the 4.9
branch.

Please submit a full bug report,
with preprocessed source if appropriate.
Reducing optimisation to -O1 or leaving out any of -mieee or -mcpu=ev4 results
in a successful compilation. While I have not checked the gcc git 4.8 branch I
note that Debian supplied gcc-4.8 compiles the file fine whereas Debian
supplied gcc-4.9 ICEs so likely to be a regression from the 4.8 branch.
I wonder if this ICE is related in any way to bug 56858.
