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
