[Bug c++/43324] New: core dump on throw

$uname -a
SunOS sigvmec2 5.11 snv_111b i86pc i386 i86xpv Solaris

$g++ -v
Using built-in specs.
Target: i386-pc-solaris2.11

--with-mpfr=/usr/local --enable-languages=c,c++,fortran --enable-shared
Thread model: posix
gcc version 4.4.3 (GCC)

Source code:
#include <iostream>
using namespace std;
int main() {
  cout << "hello world!" << endl;

  try {
    throw "exception";
  } catch ( ... ) {
  cout << "catched exception" << endl ;
  }

  return 0;
}

If I compile this with:

 g++ -m64 test.c -o test

and run ./test, I get

hello world!
terminate called after throwing an instance of 'char const*'
Abort (core dumped)

With gcc 4.3.3 it works without a problem.

Best,
Lutz

I couldn't reproduce this so far, neither on the 4.4 branch nor on mainline.
OTOH, I don't have snv_111b available here, but know that there are EH issues
on Solaris 11/x86.  I've posted a patch which works for snv_130/134, but didn't
on snv_127 and breaks Solaris 10, so I've got more investigation to do:
