The android system setting log.redirect-stdio does not seem to have any effect on ICS devices. This is a huge pain on the already painful C/C++ Native code debugging.
According to this link STDIO redirection is as simple as setting the system property log.redirect-stdio to true.

This does work on pre-ICS devices but not on anything on or past ICS. Google = bug king!
