In the modified program, calls to fflush are missing, but they are missing from
the C routine. The library does not use FILE* streams and, as far as I know, it
does its own flushing right.
The problem you mention could be avoided by a preemptive fflush(stdout), but
this is only working around the user's code problems: when you use two different
systems of I/O, you should take care that each cleans up its internal mess
before switching to the other one. gfortran did not do this properly, hence the
patch I submitted. Now, my opinion is that in the case of the code from comment
#8, it's up to the user to write his code more carefully.
As an addition to this opinion (I'll be glad to hear any other point of view),
here is a small "state-of-the-art" on this point: Intel, IBM compilers do as I
suggest here, while Portland, MIPSpro and Sun compilers do as you expect.
