Well, a bus error is a pretty horible thing to do ...

I can second this. I'v Solaris 2.6, binutils 2.10 prerelese (2000-05-02),
and the following statically-linked tests fail, all of them with a bus
error:

	21_strings/append.cc
	21_strings/ctor_copy_dtor.cc
	21_strings/element_access.cc
	21_strings/insert.cc
	21_strings/substr.cc
	23_containers/bitset_ctor.cc
	27_io/ios_members.cc

There was some discussion about that on one of the lists, IIRC.
