First, you should try android-porting, not android-ndk Do you know what the code that crashes does exactly? You should have a stack trace that tells you where the problem is located, which might give you some ideas. What compiler flags are you using when building with the gcc-4.4.0 toolchain. Not using the correct one is going to produce invalid machine code (that's why there is an NDK in the first place). Also, keep in mind that Tegra2 doesn't support NEON or VFPv3-D32 (but you would get a SIGILL fault instead, so it's probably unrelated).
