[Bug middle-end/31068] New: ICE at -O1 -fipa-pta

["fxcoudert at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

I saw the -fipa-pta option in the GCC manual, and decided to try it on
mainline. But... I can't get it to work with any C code (or Fortran):

$ cat a.c
void foo() { ; }

$ gcc -c -O1 -fipa-pta a.c
a.c: In function ?foo?:
a.c:5: error: stmt (0x2a983e4140) marked modified after optimization pass: 
return;
a.c:5: internal compiler error: verify_ssa failed

bonzini suggested I asked Daniel if it was expected or not, so... here it is.
