Description Tobias Burnus 2007-03-20 17:37:34 UTC 
In the following program, the uninitialized "i" is only detected if one uncomments the print statement.

program test
implicit none
integer :: i,j
j = i*5
print*,i
end program test
Comment 1 Tobias Burnus 2007-03-20 17:38:26 UTC 
Forgot to write that this is a Fortran program. Use
  gfortran -Wall -O
to compile it.
Comment 2 Andrew Pinski 2007-03-20 17:43:00 UTC 
And the issue here is really PR19430

For some reason gfortran decided that print will cause a pass via reference :).
