>Description:

g++ crashes when compiling the code below with -O2:

$ g++ -O2 -c x.cc
x.cc: In function `void local_to_global()':
x.cc:15: internal compiler error: in cp_expr_size, at cp/cp-lang.c:304

>How-To-Repeat:

--------------------------
struct allocator
{
  allocator(const allocator&);
};

struct basic_string
{
  allocator 	_M_dataplus;
  basic_string(const char*);
  basic_string& operator=(const basic_string& __str);
};

struct XGSIllegalDimension
{
  XGSIllegalDimension(const basic_string whose) {}
};

void local_to_global()
{
  throw XGSIllegalDimension("xxx");
}

 SEND-PR: Leave "Confidential" as "no"; all GCC PRs are public.

 SEND-PR: non-critical Report indicates minor problem.
 SEND-PR: medium       The problem should be solved in the next release.
 SEND-PR: low          The problem should be solve in a future release.
 SEND-PR: doc-bug          The documentation is incorrect.
 SEND-PR: accepts-illegal  GCC fails to reject erroneous code.
 SEND-PR: rejects-legal    GCC gives an error message for correct code.
 SEND-PR: wrong-code       The machine code generated by gcc is incorrect.
 SEND-PR: ice-on-legal-code   GCC gives an Internal Compiler Error (ICE)
 SEND-PR:                     for correct code
 SEND-PR: ice-on-illegal-code GCC gives an ICE instead of reporting an error
