Internal compiler error in `scope_die_for'

[Michal Miroslaw <mirq at nemezis dot ipan dot lublin dot pl>]

Compilation stops with message:
(gcc 2.95.2)
stdio.hh:40: Internal compiler error in `scope_die_for', at dwarf2out.c:7797
(gcc 2.95.3)
stdio.hh:40: Internal compiler error in `scope_die_for', at dwarf2out.c:7804

Files which have shown this error were mixed sources of two (very
different) versions of my library. They should not compile.
The error doesn't show if option '-ggdb' is removed.
EGCS version of gcc doesn't recognize '__restrict' in system headers
used to compile this code and fails with error:

(gcc egcs-2.91.60) (gcc egcs-2.91.66)
stdio.hh:35: confused by earlier errors, bailing out

fragment of gcc/dwarf2out.c (lines 7798-7808):
