[Bug target/20093] New: [4.0 Regression] 23_containers/deque/cons/2.cc execution test fails on ia64-hpux, -milp32

[jsm28 at gcc dot gnu dot org]

The libstdc++ test 23_containers/deque/cons/2.cc execution test fails on
ia64-hpux with -milp32 (but not with -mlp64).  This is a regression from 3.4.x.

The particular test function which fails is test_copy_ctor_exception_safety
but I haven't reduced the test to a form not depending on the libstdc++
testsuite infrastructure.

Further cut-down testcase

This test no longer depends on libv3test or the testsuite headers.
It passes with -O, segfaults with -O2 or -O -fforce-mem.
