--- Comment #1 from Richard Henderson <rth at gcc dot gnu.org> 2012-04-18 19:16:41 UTC ---
Some poking about suggests that it's too aggressive caching inside jit.c.
The test


jit_breakpoint_re_set_internal (struct gdbarch *gdbarch,
                                struct jit_inferior_data *inf_data)
{
  struct minimal_symbol *reg_symbol, *desc_symbol;
  struct objfile *objf;
  struct jit_objfile_data *objf_data;

  if (inf_data->objfile != NULL)
    return 0;


triggers and fails to re-examine the symbol after
svr4_relocate_main_executable.
