Package: gfortran-4.4
Version: 4.4.5-8
Severity: normal
Tags: upstream
gfortran does not report Error o Warnig for type mismatch in calls and
data statements (see example). When an integer is assigned in a data statement
to a double precision it performs as expected, but when a real is used it
introduces round off errors instead of padding zeros
When the mistmatch is the call of a subroutine it completely fails, the
compiler SHOULD indicate Error. Here is a test program
C test of bugs
double precision q(3)
data q/0.16D00,0.08,11/
print *,(q(i),i=1,3)
q(1)=q(1)+1
call malo(q)
end
subroutine malo(q)
real q(3)
print *, (q(i),i=1,3)
return
end
+++++++++++++++++++++++++++++++++++++++++
Compiles without warnigs with -Wall switch;
Compiles with warnigs with -Wconversion, but it places the wrong statements
at the level of the legal addition of double precision and integer!!!
