$ gfortran -g -fbacktrace -ffpe-trap=invalid u3.f90 && ./a.out

Program received signal 8 (SIGFPE): Floating-point exception.
Backtrace for this error:
  + /lib/i686/cmov/libc.so.6 [0xb7ce1208]
  + /lib/i686/cmov/libc.so.6(__libc_start_main+0xe0) [0xb7ccd030]

If you remove -fbacktrace and catch the SIGFPE with gdb, what is the gdb backtrace?
