Interesting. Are you using trunk/CC or BB? I had random (seldom)
crashes on my router, but these seem to have gone away after switching
to libstdcpp. I didn't backport it yet to BB though.

My main router also does not have mips16 enabled (built using gcc
4.6), so I can't test that issue easily, but I'll disable it
regardless - the gains of mips16 are questionable anyway. This is also
blocking 1.6.0 for now, as 1.6.0 requires C++11 support, which 4.6
doesn't provide, and I want to at least run it for a few days 24/7
first.
