pdb_print_ctypes.py "list index out of range" with Windows 7 x86 SP1 kernel on _OBJECT_REF_INFO #20

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Running the following command leads to a crash. The same command (with width=8) 
run against the x64 kernel does not seem to have a problem

./pdb_print_ctypes.py --width=4 
7/x86_sp1/ntkrnlmp.pdb/00625D7D36754CBEBA4533BA9A0F3FE22/ntkrnlmp.pdb
