--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
The Ice appeared between revisions r199034 (2013-05-17):
pr67900.f90:4.33:
function f_real(x)
1
pr67900.f90:9.36:
function f_integer(x)
2
Error: Binding label 'x' at (1) collides with global entity 'x' at (2)
and r199221 (2013-05-17, ICE). Likely one of the revisions r199118, r199119, or
r199120 (pr48858 and pr55465). I did not follow the convoluted arguments, but
the code may be invalid: see the audit trail of the two PRs. Good Luck!
