considerably ;). I have narrowed it further to the call of max_cstring_length, but of course this is merely the location where it is noted something is wrong, not necessarily the cause. Hi Arjen: Your experiments appear to have nailed exactly where the issue was. So much thanks for that work! As a direct result of that work I discovered I had forgotten an essential slice specification in the call to max_cstring_length which I have now fixed (commit 70ec495). As a result my strong expectation is your next test of Fortran example 1 for the allocated length and size case will give perfect results for both modern gfortran and ifort. By the way, this fix has nothing to do with the gfortran-4.9.2 issue where the allocate length and size command in plget_arguments_dynamic (that already works for your modern gfortran and ifort cases) overflows when doing a simple internal calculation of the amount of memory needed. I double-checked with gdb that the length and size are properly defined for that allocate command. Therefore my conclusion must be that gfortran-4.9.2 is just plain broken for such allocate commands (while your ifort and more modern gfortran are obviously not broken in this regard).
