>Description:
Exception handling in 3.0.2 works, in 3.0.3 it fails.

I could not make the example below fail when everything
was in one file, so I kept it split up into three small
files.
>How-To-Repeat:
CPP = gcc-3.0.3
CPPFLAGS = -g -fPIC -D_REENTRANT -DDEBUG -D_GNU_SOURCE

exTest: exTest.cpp LogTest.h LogTest.o TestException.h
    ${CPP} exTest.cpp -o exTest ${CPPFLAGS} LogTest.o

LogTest.o: LogTest.cpp LogTest.h TestException.h
    ${CPP} LogTest.cpp -c -o LogTest.o ${CPPFLAGS}

******** TestException.h **********
#ifndef _EXCEPTION_H
#define _EXCEPTION_H

#include <string.h>

class TestException {
protected:
    char msg[1024];

public:
    TestException(const char *errorMessage) {
        strcpy(msg, errorMessage);
    }

};

#endif

******* LogTest.h **********
#ifndef _LOG_H

    void init()
        throw(TestException);

};

#endif

********* LogTest.cpp ***********
#include "LogTest.h"


LogTest::LogTest() {

//void LogTest::init(const char* logName, bool truncate)
void LogTest::init()
    throw(TestException) {
    throw TestException("Log blah");
}

******** exTest.cpp *********
#include <stdio.h>

Use the make targets provided.
./exTest
will abort.
