Hmmm. Partitioning unshares string constants and I suppose ipa-cp propagates
one of it to the callee.
Not sure if this is a well-defined testcase though. If it is we'd probably
need to add CONST_DECLs for address-taken constants and register them with
the varpool (and disallow &"..." in gimple).
It should be possible to make a non-LTO testcase that fails similarly
by instructing the assembler/linker not to merge strings.
Joseph, does C require that a string literal "..." has a single underlying
object or would the testcase be undefined?
