When compiling this stripped down fragment of code:
subroutine dmnwgenod()
integer dmnwmaxno,dmnwmaxme
Parameter ( dmnwmaxno = 600000,
> dmnwmaxme = 200 )
integer dmnwmemli(dmnwmaxme,dmnwmaxno),
> dmnwnodco
common / dmwpnodes / dmnwmemli,
> dmnwnodco
integer nodmco,nodwml(dmnwmaxme)
integer i,mnodiid,dmvwmaiid
do 110 i=1,nodmco
nodwml(i) = dmvwmaiid(dmnwmemli(i,mnodiid))
110 continue
return
end
c: if dmnwnodco is deleted from the integer definition and the common block,
this subroutine compiles!
Command to compile:
gfortran-4.3 -m64 -O -c -fimplicit-none -fno-underscoring -fno-automatic
-Wuninitialized error.f
System:
gfortran -v
Using built-in specs.
