This is in printf and addr = -32768. Obviously nothing is
mapped there, but ...

Dump of assembler code for function printf:
    0x00000000014bdae0 <+0>:     save  %sp, -192, %sp
    0x00000000014bdae4 <+4>:     sethi  %hi(0x1c77800), %g1
    0x00000000014bdae8 <+8>:     stx  %i1, [ %fp + 0x887 ]

The frame pointer looks wrecked, but it seems strange that
this memory access would resolve to -32768.
