Thread model: posix

>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
#define _LOG_H

#include "TestException.h"

class LogTest {
protected:

public:

    LogTest();

    ~LogTest() {};

    //void init(const char* logFile, bool truncate, bool doChown=true)
    //void init(const char* logFile, bool truncate)
    //void init(const char* logFile)
    void init()
        throw(TestException);

};

#endif

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


LogTest::LogTest() {
}

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

******** exTest.cpp *********
#include <stdio.h>
#include <string.h>
#include "LogTest.h"

int main(int argc, char** argv) {
    LogTest log;
    try {
        log.init(); // aborts
        //log.init("msg"); // aborts
        //log.init("msg", true); // aborts
        //log.init("msg", true, true); // aborts
    } catch(TestException e) {
        printf("caught\n");
    }
    return 0;
}

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

>Fix:
downgrade to 3.0.2
