Description Tobias Burnus 2008-08-23 16:57:47 UTC 
For the following gfortran should print:
  "Intrinsic TRANSFER at %L has partly undefined result: "
  "source size %ld < result size %ld
but this does not work.

character(len=20) :: str
str = transfer(10,str)
end

Ditto for character( KIND=4  ,len=20)

I have a patch.
Comment 2 Dominique d'Humieres 2011-08-05 22:59:15 UTC 
The commit seems to have gone to "[Bug middle-end/37221] Missed early loop-unroll optimization - causes 40% degradation on SPU".

On Linux/x86, I got

Excess errors:
