The polyhedron test "aermod.f90" fails with:
aermod.f90: In function 'wake_dfsn2':
aermod.f90:37741: error: unrecognizable insn:
(insn 574 3142 575 38 (parallel [
(set (reg:V4SF 188 [ vect_cst_.30783 ])
(reg:V4SF 1847))
(unspec [
(const_int 0 [0x0])
] 196)
]) -1 (nil))
aermod.f90:37741: internal compiler error: in instantiate_virtual_regs_in_insn,
at function.c:1564

with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
I think it is the same bug. Has it a chance to be fixed for 4.3.0?
