Never mind. The strange thing is that it isn't behaving according to
IEEE specs, because according to those, default behaviour on fp
exceptions is to set a flag and continue. 

I bet the exception is happening in InitArithmetic() in
src/main/arithmetic.c which does some division by zero *before*
setting a signal handler for SIGFPE. Tried running it under the
debugger? (or debugging the core file?)
