I'm not very familiar with emacs internals or how to investigate this
sort of thing. I starting gdb with `gdb --core=core /usr/bin/emacs`
(I'm not sure if that is right). Here is the data at those
addresses(I'm not sure what else I could do...unfortunately this looks
fairly useless):

(gdb) x/16w 137657473
0x8347c81 <my_endbss+83781>:    0x9b000000      0x81081e8c      0x8408338e      
0x8347c91 <my_endbss+83797>:    0x00083404      0x10000000      0xb3000000      
0x8347ca1 <my_endbss+83813>:    0x8108338e      0x7508338e      0x00083404      
0x8347cb1 <my_endbss+83829>:    0xcb000000      0x81081e8c      0x8108338e

I found an eval.c file on my computer and tried:

(gdb) frame 4
#4  0x08185c1c in Fsignal (error_symbol=137657473, data=151680309) at 
1543          if (bp && bp->function && EQ (*bp->function, Qerror))

but that file is probably is probably out of date, and the output
isn't really useful anyways... I'm out of ideas on what to do from
