           Summary: *reinterpret_cast<std::string *> causes ICE
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: jfc at legra dot com
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i686-pc-linux-gnu
  GCC host triplet: i686-pc-linux-gnu
GCC target triplet: i686-pc-linux-gnu

I tried to make a fake std::string value using reinterpret_cast and got a core dump.

Source:
#include <string>
std::string fakefoo()
{
  return
  ({static char rep[] = { "\0\0\x00\x04\0\0\x00\x04\0\0\0\0" "foo?"};
   struct { void *p; } p = {&rep[12]};
   *reinterpret_cast<std::string *>(&p);})
    ;
}

With gcc 3.3 on i386-linux I get
str.ii:5700: internal compiler error: in cp_expr_size, at cp/cp-lang.c:312

with gcc 3.2.1 or gcc3.2.2 on Linux, mips, or SPARC I get
str.ii:5700: Internal compiler error in simplify_gen_subreg, at simplify-rtx.c:
   2711

This happens regardless of optimization level.
