You're welcome.

My money is on exceptions.   Compile with -fno-exceptions and see if 
it shrinks.

Stripping .o's before handing them to the linker can't be a good plan.
It's not actually gcc that drops core.   It's ld/collect2.   Stick a 
debugger in it and see if you can give better hints.

Yes, I really need to go build a current gdb...

I, too, am amazed at the speed things are moving on this list.
