--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed but as Martin notes likely a dup of the tree-sharing issue(s). With
-fno-checking:
> ./cc1plus -quiet t.ii -O -fno-checking
during GIMPLE pass: cddce
t.ii: In member function ‘void DateFormatTest::TestNonGregoFmtParse()’:
t.ii:46:1: internal compiler error: tree check: expected ssa_name, have
addr_expr in mark_operand_necessary, at tree-ssa-dce.c:162

Maybe that's going to prevail (and new fallout of my gsi_remove changes).
