! Test the fix for PR34438, in which default initializers
! forced the derived type to be static; ie. initialized once
! during the lifetime of the programme. Instead, they should
! be initialized each time they come into scope.

! Contributed by Sven Buijssen <sven.buijssen@math.uni-dortmund.de>
! Third test is from Dominique Dhumieres <dominiq@lps.ens.fr>
