curious. looks like an issue with the | option...  afaics the main

IO::stream[static_cast<int>(fileno(to_pipe))] = to_pipe;

im wondering why child process and file are handled differently.
(i have no idea, what IO::stream is supposed to do -- maybe Al will
explain on gnucap-devel.)

timing is not an issue. something is closing the pipe, killing your

gnucap has some tolerances you could change. also you could exchange the
integrator (see manual). but it won't fix the problem.
