Psymtabs do not come from the ELF symbol table; they come from a first
pass over the DWARF information. So, if this warning triggers, that
pass must have done something bogus.

"maint print psymbols" and "maint print symbols" might be useful;
the interesting question is, what psymtab thought it covered the
address, and why didn't the corresponding symtab?

Oh, one frequent cause is mis-estimating the range of addresses covered
by the psymtab.
