Native code is passed an int (in a 64 bit register) which has some bits set in the upper 32 bit half. The native code uses that value for an address computation. That results in a wrong memory access. From a few experiments with code generated by gcc, it seems it expects values to be clean on function entry. The fix cleans the 32 bit value before the native call.
