This exception was probably thrown by a direct check for NaN in
ecl_make_singlefloat. The native FPE exceptions are mainly needed for
compiled and c-inline code that writes directly to floating-point
arrays.

By the way, that 'static int last_bits' in si_trap_fpe is not very
thread-safe. This value probably should be in the environment
structure, because exception configuration is independent for
different threads.
