I just recompiled r258097 and I still get it:

$ xgcc -x c++ -S -
[...]
<stdin>:3:9: internal compiler error: tree check: expected record_type or
union_type or qual_union_type, have array_type in
reduced_constant_expression_p, at cp/constexpr.c:1778

$ cc1plus -version

GGC heuristics: --param ggc-min-expand=30 --param ggc-min-heapsize=4096

Is there anything else I can do (for example any other information I can give)?

I tried running it under valgrind --trace-children=yes and it gives 0 errors.
