[panda-users] taint segmentation fault

[xiaojuan Li]

ok.
1.I want to use taint plugin to get information about some functions(of
course, it is closed-source),so I think I can stringsearch potential data
and then taint them and next I can locate the functions which solves these
data.

2.the command line I used is : stringsearch:name=***;
taint2:tainted_instructions=1.

thanks
