[panda-users] taint segmentation fault

[Brendan Dolan-Gavitt]

Could you provide:

1. What information you're trying to get
2. The command line you're using to run PANDA with the taint2 plugin

?

Right now I believe taint2 does not produce very much output by default.
Instead you use the -pandalog <filename> command line option, and taint2
will write its results there in pandalog format; you can then read them
using pandalog_reader (see panda/pandalog_reader.c for details on that
tool).
