>Description:
gcc-2.95.2 installed from pkgsrc cannot catch any exception of C++.

Probably, -fno-sjlj-exceptions option is default,
but EH frame is not initialized.

>How-To-Repeat:
NG case:

% cat a.cc
#include <iostream>

int
main()
{
  try {
    throw int(10);
  } catch(...) {
    cerr << "exception is raised." << std::endl;
  }
  return 0;
}
% /usr/pkg/gcc-2.95.2/bin/g++ a.cc
% ./a.out
zsh: 9487 abort      ./a.out


OK case:

% /usr/pkg/gcc-2.95.2/bin/g++ -fsjlj-exceptions a.cc
% ./a.out
exception is raised.


>Fix:
flip the default of -fsjlj-exceptions?
