Re: GDB 6.5.90 available for testing (GDB 6.6 pre-release)

[Jim Blandy <jimb@codesourcery.com>]

Here's the patch I've been using for this.  It'd be better to rework
the way those functions use those obstacks, but...

2006-12-05  Jim Blandy  <jimb@codesourcery.com>

      * cp-valprint.c (cp_print_value_fields, cp_print_value):
      Initialize tmp_obstack, to avoid warnings.
      * p-valprint.c (pascal_object_print_value_fields)
      (pascal_object_print_value): Same.
