I just tried the attachment in the PR.  It seems to work fine on
i386-unknown-netbsdelf on gcc-current (I have several NetBSD
configuration changes that I have not yet submitted to the GCC
folks, so maybe my compiler is behaving a bit differently than yours).

dr-evil:thorpej 1103$ i386-unknown-netbsdelf-c++ exc.ii -o exc 
dr-evil:thorpej 1104$ ./exc                                                    
dr-evil:thorpej 1105$ 

What version of NetBSD are you using?  You need to have crtbegin/crtend
files that support DWARF2 exception handling...

It also works with NetBSD-current's GCC 2.95.3-based toolchain:

dr-evil:thorpej 1105$ c++ exc.ii -o exc
dr-evil:thorpej 1106$ ./exc
dr-evil:thorpej 1107$
