yes, I am using '-ffpe-trap=precision,zero'

(full options: -mtune=i586 -O0 -m32 -static -Wall -fbacktrace
-ffpe-trap=precision,zero -g -fstack-check -fstack-protector-all
-Wstack-protector )

this is the backtrace by gdb:

So logging.f90:361 just contains:
     call CPU_Time(CpuTimer_Reset)

(real, save :: CpuTimer_Reset)

Is this a problem of the cpu_time intrinsic or does the error actually
already occur before?
