--- Comment #3 from Paul Thomas <pault at gcc dot gnu.org> ---
Out of 79 tests gfortran.dg/pdt*.f*, the following leak memory:

pdt_2.f03 - should fail in runtime and so leaks memory.

pdt_3.f03, pdt_39.f03 - sources of memory leaks are marked as comments

pdt_70.f03 - fails with memory allocated from line 108: call alloc_ts(c) 

pdt_77.f03 - not investigated in detail yet.

A common theme appears to leaks caused by allocations of PDT with source.
