David,

I have not done a full bootstrap and I am still testing, so treat these as 
prelimary findings:

The patch appears not to fix the abort on try/catch.

However with the patch, I am not getting imports of __GLOBAL__F* from 
libstdc++ into my shared library. So maybe it is a fix to part of the problem?

I'm not sure if the original problem is that the libstdc++ library exports the 
__GLOBAL__F symbols or that the user library imports and uses them?

In the patch, should it be checking the variable shared_obj or is_shared?
I think that it would depend where you class the problem: shared_obj to fix 
libstdc++, is_shared to fix user library.

Thanks for your help.
I will update again when I feel I have properly tested the patch.

Regards,
Andrew.
