Hi!
This a very minor thing, but it turns out to be a bit annoying: gfortran now
and then (rather randomly in my opinion) throws this compilation diagnostic, of
which I don't seem to make head or tail:
warning: '<anonymous>' may be used uninitialized in this function
This warning looks quite meaningless to me (at best).
Cheers!
Philippe
PS: gfortran -O1 -g -Wall -c Source.f90
Source.f90: In function 'test':
Source.f90:35: warning: '<anonymous>' may be used uninitialized in this
function
PPS: don't look for much sense, I just tried to cut down some valid sources
while keeping this behaviour...
