lto1: internal compiler error: in strip_extension, at lto/lto.c:910

lto-wrapper: /usr/local/gcc45/bin/gcc returned 1 exit status
/usr/bin/ld: fatal error: lto-wrapper failed
collect2: ld returned 1 exit status

It fails trying to strip ".o" from "liba.a". (I added an extra line to print
that, so the ICE line number is off by 1.)
Using gcc 20100314 and gold from Ubuntu binutils-gold 2.20-0ubuntu2.

Confirmed.  -fwhopr seems to be broken with respect to ar archive support.
I don't see any reason to strip extensions at all.  Which then get's us to

lto1: internal compiler error: compressed stream: data error
Please submit a full bug report,

likely again because of lack of archive support somewhere.
