[Bug c++/24906] New: ICE When using -fmudflap on a simple C++ source file

["martin dot audet at imi dot cnrc-nrc dot gc dot ca" <gcc-bugzilla@gcc.gnu.org>]

Hi,

I get the following message when I try to compile a simple C++ source file
using strings:

strbug.cpp: In member function 'void AClass::meth(AClass::AnInterface&)':
strbug.cpp:17: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://bugzilla.redhat.com/bugzilla> for instructions.
Preprocessed source stored into /tmp/ccvs6PL2.out file, please attach this to
your bugreport.

This happens when I compile as follow:

g++ -Wall -fmudflap -c strbug.cpp

Without the -fmudflap flag, there is no ICE.

The corresponding source file is:

#include <string>

class AClass {
private:
   std::string name;

public:
   class AnInterface {
   public:
      virtual bool intf_meth(AClass &p_aclass) = 0;
      virtual ~AnInterface(void) { }
   };

   void meth(AnInterface &p_interf);
};

void AClass::meth(AnInterface &p_interf)
{
   name = std::string();

   p_interf.intf_meth(*this);
}

I did not included the preprocessed source file since it is more than 19k lines
long.

Note also that I'm using Fedora Core 4 Linux with the gcc update installed
(this is why it is version 4.0.1).

Regards,

Martin
