Comment (by bgamari):

 I'm now looking specifically at the crashing function (`getCallStack`): I
 can confirm that the argument is completely crazy:
 {{{
 >>> ghc closure $r14
 off-heap(0x400c5dd8)
 >>> ghc symbol 0x400c5dd8
 8 bytes into base_DataziData_zdfDataAnyzuzdcgunfold_closure (starts at
 0x400c5dd0)
 }}}
 That is, the argument is an off-heap value that doesn't even begin on
 defined symbol. Sheer madness. Let's try to see why.
