gcc-2.95.3: exceptions from shared libraries result in abort

[Dimitris Vyzovitis <vyzo at media dot mit dot edu>]

I have problems with handling exceptions thrown from shared libraries. In 
particular, any exception thrown by one of my shared libraries will 
result in a core dump, even though I have suitable exception handlers.
My gcc is "gcc version 2.95.3 20010315 (release)" and was compiled with 
--enable-shared. binutils is 2.11.90.0.1

Here is a small test case, together with the compilatio/linker flags I use.
Am I doing something wrong or is this a bug?

### File: tlib.h
struct tlib {
  void doit();
};

### File tlib.C
#include "tlib.h"

void tlib::doit() {
  throw "something";
}


### Shared library is compiled with:
$ g++ -fPIC -c testtlib.C
$ g++ -L. -ltlib testtlib.o -o testlib

### Test progarm: testtlib.C
#include <iostream>
#include "tlib.h"

int main() {
  try {
    tlib t;
    t.doit();
  } catch ( ... ) {
    cerr << "Exception!" << endl << flush;
  }

}

### test program compiled and linked with
$ g++ -fPIC -c tlib.C
$ g++ -L. -ltlib testtlib.o -o testlib


Running the program simply results in core dump, despite the presence of 
the default exception handler.
