    By default, gcc will emit armv5t instructions. What's your target CPU?
    init segfaulting can be a symptom of using a bad instruction set, so if
    your CPU is armv4, and you did not tell gcc to default to armv4, then
    you will hit this segfault issue.



As I already mentioned, it works fine with uClibc, so it is definitely 
not a CPU instructions issue. At any rate, my CPU is AT91, i.e. armvte 
instruction set.
