It appears to still be there with the latest released 3.4 compiler. I didn't
take the time to build a native compiler for my target, just the cross compiler
hosted on my Red Hat system.

[root@tanith root]#

On my target wich is a small p3 board.

bash-2.05# ./throw2
Aborted
bash-2.05#

On an older 3.2 based compiler replacing the libstd++.so.* files with ones from
a compiler built with i585 target caused the abort to go away. Also, removing
the libstd++.so.* files so that this one library is linked static caused the
abort to go away.

Removing the libstd++.so.* libraries does not make the abort go away on the 3.4
compiler, but -static still does.
