Hi,

I've got some changes to the C++ front end that I've tested pretty
well (make check-g++).  Then, I updated the compiler and rebuilt from
scratch in preparation for final testing and check-in.  Now, every
dynamically linked C++ binary crashes, but statically linked ones are
OK.

The behavior is somewhat odd; GDB seems to get confused:

bash-2.05$
LD_LIBRARY_PATH=/home/mitchell/dev/gcc-mainline/objdir/i686-pc-linux-gnu
//libstdc++-v3/src/.libs:. ./bitfield1.exe  Segmentation fault

Interesting.

I found the bug -- it was in my changes to the C++ front end -- but I
very much appreciate all the debugging tips.
