------- Comment #3 from vmakarov at redhat dot com 2008-05-06 19:11 -------
Thanks for decreasing the test case. The problem was in wrong mode of
save/restore stack slot when it was reused for another hard register. It
resulted in generation of wrong save/restore insn and after that in a wrong
secondary reload insn needed for this insn and the last insn caused a crash in
the postreload pass.
The patch solving the problem will follow soon.
