In the attached sample code, which is a reduced test case from the full
code,
the assignment as_b = as_a leaks memory from the U(:) allocatable
component
(which is defined in state_t, the parent type), but not from the W(:)
allocatable component (which is defined in astate_t).
Sorry, I'm not able to reproduce the memory leak with gfortran version 4.5 and
valgrind. Could you please tell me which gfortran version you use and how you
detect the memory leak?
This is 4.7.0 (svn) running on OS X 10.6.7. valgrind output:
