Ditto for gcc-2.95.2-13 from Debian (potato). It exhibits the same
bug.
Debian applies a total of 49 patches to gcc and the libraries.

I am tempted to write a little script which discards the patches one
by one and re-builds and re-tests each time, and leave it going all
night.... but I'm not sure if I actually will.
