The following testcase ICEs on x64_64-linux with -m32 -O:
$ cat u.f90
subroutine scaleg(a, w)
real a(1), w(1)
a(1) = 2.0**int(w(1))
end
$ gfortran -m32 -c u.f90 -O1
u.f90: In function ‘scaleg’:
u.f90:3: internal compiler error: in copy_insn_1, at emit-rtl.c:4925
The regression happened somewhere between revisions 127363 and 127489. It
doesn't feel like it is a front-end issue, but I haven't got a C testcase for
it :)
