 The crash happens in:
 
 #0  0x0ca5af70 in get_core_register_section (
     regcache=regcache@entry=0x608688a0, regset=regset@entry=0x0,

 (gdb) p size
 $3 = 68
 (gdb) p min_size
 $4 = 0
 (gdb) p regset
 $5 = (const struct regset *) 0x0
 
 This is called from:

 with a NULL pointer as regset and 0 as min_size.
