Within the last two days, Solaris 2/SPARC got broken: cc1plus ICEs building the
64-bit streambuf-inst.lo:

Maybe this indicates that Jakub's recent patch

2011-03-16  Jakub Jelinek  <jakub@redhat.com>

    * emit-rtl.c (try_split): Don't call copy_call_info debug hook.
    * calls.c: Remove debug.h include.
    (emit_call_1): Don't call virtual_call_token debug hook.

Is the culprit?

Might be, but the testcase from Comment #5 doesn't fail for me.

Will retry tomorrow once another 4.6 bootstrap is finished.

While a C++-only bootstrap indeed completes as of rev 171126, an Ada
bootstrap still fails, but this seems to be a different error.

The failure can be reproduced with

$ gnat1 -quiet -O2 -fPIC -g g-debpoo.adb
